Corund One Stone

Listing images, Premium A+ Content and Brand Story for a pendant with one laboratory-grown blue sapphire: a round stone, 6.5 mm, in a smooth 8.3 mm bezel with an open back and a fixed hidden bail, a 1.2 mm cable chain, 18 in with a 2 in extender, and a 12 x 6 mm lobster clasp; the metal is 18K gold vermeil, at least 2.5 microns of gold over 925 sterling silver with a palladium layer between them. Of 31 galleries on the shelf, none prints the gold layer in microns and none shows a hand opening the clasp; of 20 pendants, none shows the stone in more than one light, and only one draws the length on a body. Corund answers in the order the reviews rank those fears: one image, one fear, a headline and one line. The system is mineral on mineral: the pendant lies on pale limestone by a morning window, shadows fall from the window on the left, every word is set in one warm graphite, with no badges and no digital effects; photos of people are windows cut into the stone, and the headlines stay on the stone. In the box: a label card that names the stone, and a tray with a 50 mm ruler. The name comes from corundum, the mineral the stone is made of. The brand is fictional; the listing is complete, built for the US with notes for the EU, to show the same method in a ninth category.

Cover

Corund One Stone, a pendant with a laboratory-grown blue sapphire, under the words Grown, not mined. The cover is a spread from a jewelry lookbook: on the left, the neck with the pendant on the 18 in chain, the photo a window cut into pale limestone; on the right, on the stone, like a title page, Corund set large, one line about the work and what is inside. Then the idea in one panel, 'Mineral on mineral.': the pendant lies large on the same stone, the chain runs off the top edge, the shadows fall from the window on the left, a 5 mm bar beside it and one line: one light, one stone, and only the numbers that can be checked.

The idea, 'Mineral on mineral.': the Corund pendant large on limestone, the chain running off the top edge, shadows from the window on the left, a 5 mm bar and one line about the system

Brief

'What almost no pendant on the shelf shows.' Of 31 galleries on the shelf (20 pendants and studs, 11 close alternatives), none prints the gold layer in microns and none shows a hand opening the clasp; of 20 pendants, none shows the stone in more than one light, and only one draws the length on a body. Under those four gaps, the buyers' eight questions in the reviews' order, each with the number of the tile that answers it: is it really silver and gold, how big is it on me, what exactly is the stone, can I open the clasp myself. Three concepts, Corund, Plinth and Anneal, went to three judges: the seller and shopper, the art director, and production with the rules. All three put Corund first, 117 of 150 against 101 and 90, and it took the best of the other two: '6.5 mm, beside a fingertip.', the 5 mm bar on enlarged frames, the ruler on the box tray, 'Last on, first off.' and care without silver dip or polishing compound. The idea stayed the same; after the proofs, the look settled on limestone by a window.

Three concepts and three judges: Corund 117 of 150, Plinth 101, Anneal 90, all three put Corund first; what it took from the other two and what changed after the proofs

Object

'One stone in a plain bezel, seen from five sides.': five views on the stone at one scale, rhodium-plated silver, vermeil, the back stamped 925, the hidden bail in profile and the 12 x 6 mm clasp. The main image is the pendant on pure white, stone to the lens; without its shadow the piece fills 88% of the frame. And the piece in five lines: the stone, one round laboratory-grown blue sapphire, 6.5 mm; the bezel, 8.3 mm across and 3.7 mm deep with the stone, open at the back; a 1.2 mm cable chain, 18 in plus a 2 in extender; a 12 x 6 mm lobster clasp; the metal, 18K gold vermeil, 2.5 microns minimum, over 925 sterling silver, 'Not solid gold'.

System

'One surface, one light, few words.' The surface is limestone, a different piece of it under every image but the main one; the light is a window on the left, the stone 5% darker at the right edge, measured; the shadow sits under every piece in four layers; the type is Libre Caslon Display for headlines and Manrope small capitals for lines; the ink is one warm graphite, #2A2724, for every word and line; the words are a headline and one line, or two or three short captions, 12 to 28 words a tile, counted. 'Nothing on the stone that a window could not make.' Then color by the numbers: the vermeil and the silver on the stone, and the same pixels in gray. The stone holds 7.14:1 against the limestone; the vermeil rim alone gives 1.52:1, so the gold is held by its dark band and its shadow, 5.65:1 on tile 08; the ink gives 10.9:1. And skin by frame: the neck, the fingertip and the ear in color and in gray, measured.

Color by the numbers: the vermeil and silver on limestone and the same pixels in gray, with the contrast of the stone, the rim, its dark band and the ink; the skin of the neck, fingertip and ear in color and in gray, measured

Gallery

'Nine images, one surface.': nine slots at 2000 x 2000, each tile answering one fear in the order the reviews rank them, with a headline and one line, and the swipe never shows two close-ups in a row before a person. 'Where it sits, at 16, 18 and 20 in.': three lengths on one neck, the photo a window in the stone; one gallery in 20 draws a length on a body. '18K gold vermeil, measured in microns.': the metal in section, drawn thicker than life and saying so, beside the back stamped 925 and 'Not solid gold'; no gallery on the shelf prints microns. '6.5 mm, beside a fingertip.': the pendant on a fingertip and a 10 mm ruler at the scale of the hand. 'One stone, three lights.': the same stone in daylight, under a warm lamp and in open shade; in the market sample, stone color draws 95 mentions, 30 of them negative. 'A lever you can press with a thumbnail.': the 12 x 6 mm clasp in two hands. Then care as habits, 'Last on, first off.', with the whole necklace laid on the stone; 'Grown, not mined.': crystal, cut stone and pendant at one scale, the crystal labeled as an illustration; and 'Every piece comes with its label.': a slide box with a 50 mm ruler on its tray, the label, the metal and care cards and a pouch. Among the market's 40 gift-box quotes: 'came in a ziplock bag, no box'.

Tiles 02 and 03 large: three lengths on one neck, 16, 18 and 20 in, and the metal in section with its microns beside the back stamped 925

'One stone, three lights.': the same stone in daylight, under a warm lamp and in open shade as three tall windows, tile 05 below

Tiles 04 and 06 large: the pendant on a fingertip with a 10 mm ruler, and the clasp opened with a thumbnail

Tiles 07, 08 and 09: care, 'Last on, first off.'; 'Grown, not mined.', crystal, cut stone and pendant; and the box with its label and the ruler on the tray

On the body

'On the body, at its true size.': four windows in different proportions, the neck with the pendant on the 18 in chain, a fingertip with the pendant on it, an ear with the set's 5 mm stud, and two hands with a thumbnail at the clasp lever. The casting rule in one line: adults, honest skin with pores and freckles, short unpainted nails, no other jewelry, nobody looking into the lens. And 'One stone, the same in every frame.': twelve frames of one stone, the studio, three-quarter, the back, in silver, warm lamp, open shade, the neck, the fingertip, the ear, care, grown, cut, set, and the box, with the client's numbers below: 9 gallery images, 7 A+ modules and 79 of 81 checks; the two that stay open are release gates, the stone's weight in carats and the piece's weight in grams wait for the client's sample.

One stone in every frame: twelve squares of one stone from the studio to the box, with the client's numbers, 9 gallery images, 7 A+ modules, 79 of 81 checks

Premium A+

'Seven modules, below the fold.': seven modules 1464 px wide in a row on the same limestone, each with a 600 x 450 mobile variant with the words set larger for the small screen. 'One stone, named in full.'; 'Grown, not mined.', what a laboratory-grown sapphire is: the same corundum that comes out of the ground, grown as a crystal, by a method known since 1902; four details you can check, the bezel all the way round, the open back, a bail that keeps the pendant facing forward, a lever for a thumbnail; 'What it is made of.', the metal in section beside the back; the sizes in inches and millimeters; silver, vermeil and the set in one chart, 'Silver, vermeil, or the set.'; and nine questions as live text, not as an image. 'Where most of them read it: a phone.': slot 02 at phone width with the metal bullet, and the A+ mobile variants.

On a phone: slot 02 with the headline, price and the metal bullet, and the A+ mobile variants on three phones

The box

'A box that measures.': a slide box whose tray carries a 50 mm ruler with two ticks, 6.5 and 8.3 mm; lay the pendant on it at home and the box answers 'how big is it'. On the panel: tile 09 as a print, the label card front and back (the report number is printed there and nowhere else), and the back of the pendant, stamped 925, large above the first millimeters of the ruler at the same scale, the bezel from 0 to 8.3 mm. Inside the box: the label, the metal and care cards and a pouch; no price.

'A box that measures.': tile 09, the label card front and back, and the back of the pendant stamped 925 large above the tray's ruler, ticks at 6.5 and 8.3 mm

Line

'Silver, vermeil, or the set.': a comparison chart needs neighbors, so there is a line, one stone in three versions, on the stone at one scale. One Stone, Silver (CR-65S): 925 sterling silver with a rhodium finish. One Stone, 18K Vermeil (CR-65V): this listing. One Stone Set (CR-65VS): the pendant and studs with two laboratory-grown sapphires, 5 mm each, two label cards and one slide box with two trays. The silver one has no gallery of its own: its main image and its column in the A+ 6 chart carry it. No prices on the panel.

Brand Story

'Why the mineral comes before the name.': the background is the pendant on limestone, with the boule mark in graphite and the story 'We name the stone in full.' over it: Corund comes from corundum, the mineral comes before the brand, and every piece ships with a label card, the way a mineral is labeled in a collection: the stone, how it was grown, its size and weight, and the number of its report. Then four cards, the boule, the label, one stone under three lights, the line, and the brand's three questions as live text: why Corund, why grown, why a bezel.

Copy

'What we said, and what we didn't.' Said, with the condition beside the claim: 'laboratory-grown' right before every 'sapphire', in the title, the bullets, the description, the A+, the Brand Story and the alt text; the karat before the word and the microns beside it, '925 sterling silver plated with 18K gold, 2.5 microns minimum (gold vermeil). Not solid gold.'; the stone is 'not a mined stone', and its weight and report number are on the label card; plating wears thin with time and replating is a normal service; the crystal is labeled as an illustration. Not said, though the category says it often: no 'sapphire' alone, no 'solid gold', no 'tarnish-free', 'waterproof' or 'hypoallergenic', habits instead; no healing, no meanings, no velvet, no roses, no strike-through price. The stone's weight in carats and the piece's weight in grams stay blank until the client's sample is weighed. Checked against Amazon's limits: title 73 of 75, description 1958 of 2000, search terms 186 of 249 bytes.

Checks

'At 300 px, at 100 px, in gray.': the Behance cover at 300 px beside the studio's eight other covers, and its measurements: the stone 19.4 px, the bezel 24 px, in gray the stone darker than all the skin around it, the photo 70% of the cover, the rest a limestone mount, the only one of the nine. The main image at 100 px among placeholder gray search tiles; no real listing is shown. The nine tiles in gray, with the stone's contrast against its surround. 79 of 81 automated checks against Amazon's jewelry rules passed before export; the two left are release gates, the stone's weight in carats and the piece's weight in grams wait for the client's sample, and none was invented.

From the brand

We name the stone in full.

Corund comes from corundum, the mineral our stones are made of: aluminum oxide, Mohs 9. The mineral comes before our name. Each Corund piece holds one laboratory-grown sapphire in a plain bezel and ships with a label card, the way a mineral is labeled in a collection: the stone, how it was grown, its size and weight, and the number of its report. The metal is labeled the same way, in microns. If a fact is on the label, you can check it.

Why the name Corund?

Because it is what our stones are made of. They are corundum; we put the mineral first and the brand second.

Why grown and not mined?

Because we can name every step: grown, cut, set, with a report number. A laboratory-grown sapphire is corundum, the same mineral that comes out of the ground; we price it and label it as what it is.

Why a bezel?

Because it holds the stone all the way round, leaves nothing to catch, and keeps the back open so light comes through.

Corund vermeil pendant with a 6.5 mm laboratory-grown sapphire on pale limestone, 5 mm bar

One stone, named in full.

A laboratory-grown blue sapphire in 18K gold vermeil, with a label that says what it is, how it was grown and how big it is.

Module 2 · Premium Single Image & Text

Grown corundum crystal, cut laboratory-grown sapphire and the set pendant, with a 5 mm bar

Grown, not mined.

A laboratory-grown sapphire is corundum: aluminum oxide colored blue by traces of iron and titanium, Mohs 9, the same mineral that comes out of the ground, grown as a crystal instead of dug. Corundum has been grown in a flame since 1902, when Auguste Verneuil announced the method. Ours was grown as a crystal, then cut and polished; how it was grown and any treatment are named on its label card. Every Corund piece ships with that card: the stone, its species, how it was grown, its size and weight, and the number of its report.

Module 3 · Premium Four Images & Text

Four details you can check.

Corund bezel rim around the stone, magnified, with a 5 mm bar

Held all the way round

A full bezel closes the metal around the whole stone: no prongs to catch on knitwear or bend.

Open back window of the Corund pendant, magnified, with a 5 mm bar

Open at the back

A round window about 3.8 mm wide behind the stone lets light in from behind and lets you wipe lotion out.

Faces forward

The bail is a fixed tube hidden behind the rim, so the pendant faces forward instead of turning over.

Lever of the Corund lobster clasp, magnified, with a 5 mm bar

A lever for a thumbnail

The 12 x 6 mm lobster clasp has a lever you can press with a thumbnail; hold the clasp, not the chain.

Neck with length lines for the Corund 16 and 18 in chains

Sizes, in inches and millimeters.

Length: 18 in (46 cm) plus a 2 in (5 cm) extender, measured end to end including the clasp. Also sold as 16 in + 2 in extender (41 + 5 cm). The 16 in chain sits at the base of the neck and the 18 in on the collarbones; the extender takes the 18 in chain to 20 in, just below them. To choose a length for someone else: 1 lay a necklace they already wear flat on a table; 2 measure it end to end, clasp included; 3 choose the same length, and the 2 in (5 cm) extender adds the rest. From across a table it reads as one blue point on a line of gold vermeil; at a hand's distance, as a cut stone in a smooth wall. Pendant 8.3 mm across and 3.7 mm deep with the stone. Stone 6.5 mm. Chain 1.2 mm cable.

Module 7 · Premium Q&A

Before you choose.

What exactly is the stone?

A laboratory-grown sapphire: corundum, aluminum oxide, Mohs 9, grown as a crystal and then cut. Round, 6.5 mm. Its weight in ct, how it was grown, its treatment and its report number are printed on the label card in the box.

Will the blue look like the pictures?

A laboratory-grown blue sapphire changes with the light. The fifth image shows the same stone under three light colors: by a north window, under a warm lamp and in open shade. Expect it brighter by day and deeper in the evening.

What is under the gold layer?

925 sterling silver, with a palladium barrier layer between the silver and the gold layer. The gold layer is 18K, 2.5 microns minimum: gold vermeil, not solid gold.

Will it tarnish or wear?

Silver darkens with air and sweat, and the gold layer wears thin with time and use; replating is a normal service. Put it on last, take it off first, and wipe it with the plain cloth in the box when it dulls.

Should I take it off to swim or shower?

Yes. Remove it before swimming, showering, exercise and sleep, and keep it away from perfume, lotion and household chemicals. Not on vermeil: silver dip, cloths with polishing compound, toothpaste or baking soda.

How big is it, and which length should I choose?

The stone is 6.5 mm and the pendant 8.3 mm across. The 16 in (41 cm) chain sits at the base of the neck, the 18 in (46 cm) on the collarbones; both have a 2 in (5 cm) extender. The second image shows the positions on one neck, the fourth the pendant on a fingertip.

Can I open the clasp myself?

The lobster clasp is 12 x 6 mm with a lever you can press with a thumbnail; the sixth image shows it in a hand. Unclasp it before pulling a sweater over your head: a 1.2 mm chain is jewelry, not a rope.

Will the stone fall out?

The stone sits in a full bezel: the metal is closed over its edge all the way round, with no prongs to catch or bend. A knock on a hard edge can still chip any cut stone.

What comes in the box?

The necklace in a slide box with a 50 mm ruler printed on the tray, a cotton pouch, the label card with the stone's report number, a metal card, a care card, a plain microfiber cloth and an anti-tarnish strip. No price inside.

Product description

Metal: 925 sterling silver plated with 18K gold, 2.5 microns minimum (gold vermeil). Not solid gold. Under the 18K gold layer: a palladium barrier. The gold layer is measured by XRF per lot.

Stone: laboratory-grown sapphire, 6.5 mm; not a mined stone. It is corundum, aluminum oxide, Mohs 9, grown as a crystal and then cut. Its report number is on the label card.

Length: 18 in (46 cm) plus a 2 in (5 cm) extender, measured end to end including the clasp. Also sold as 16 in + 2 in extender (41 + 5 cm).

Quality mark: stamped 925 with the maker's mark on the back of the bail.

Care: put it on last and take it off first; remove before swimming, showering, exercise and sleep; keep away from perfume, lotion, sweat and household chemicals; wipe with a soft dry cloth after wearing and store in the pouch. Gold plating and vermeil wear thin with time and use; replating is a normal service. When it dulls: thirty seconds with the plain cloth. Not on vermeil: silver dip, cloths with polishing compound, toothpaste, baking soda or ultrasonic baths; they take the gold layer off with the tarnish. If the gold layer wears thin, what shows is the 925 sterling silver core. A knock on a hard edge can still chip any cut stone.

In the box: a slide box with a 50 mm ruler on the tray, a cotton pouch, the label card, a metal card, a care card, a plain cloth with no polishing compound and an anti-tarnish strip. No price inside.

Adult jewelry, not a toy. Contains small parts: keep away from children.

Description · 1,958 of 2,000 characters

Materials

Pendant, bail, chain, clasp, extender and tag: 925 sterling silver plated with 18K gold, 2.5 microns minimum, over a palladium barrier (gold vermeil). Stone: one laboratory-grown sapphire, corundum (Al2O3). Inside the clasp: a steel spring. Box: uncoated gray board; insert: white cotton paper; pouch: undyed cotton with a drawstring; cards: white cotton board; cloth: gray microfiber with no polishing compound; strip: paper.

How to use

To open the clasp: hold the clasp, not the chain, and press the lever toward the hinge with your thumbnail. To choose a length for someone else: 1. lay a necklace they already wear flat on a table; 2. measure it end to end, clasp included; 3. choose the same length; the 2 in (5 cm) extender adds the rest. To store: wipe it dry and put it in the pouch.

Safety warning

Adult jewelry, not a toy. Contains small parts: keep away from children.

The stone's weight in ct and the piece's weight in grams, the stone's treatment line and its report (number, lab, growth method), the country of origin, the manufacturer and the US importer, the metal assay and the XRF test of the gold layer, the maker's mark beside the stamp, the lead and cadmium test and the Prop 65 decision, the EN 1811 nickel test, the UPC and the line's sibling ASINs in this concept are placeholders. The storefront leaves them out: the stone bullet and the description carry no weight, no treatment and no 'Made in' line; on the sleeve back and on the label card in the box they are blank ruled lines, and not one number is invented; ASINs are not rendered here.

What a live store adds on top of this: its own interface, reviews, ads and Buy Box logic. None of that is listing design. Everything above this line is.

What changed from Amazon

Images at 2200 × 2200, the size Walmart asks for (Amazon: 2000).
Walmart allows no benefit claims on images, so only facts stay: doses, steps, ingredients.
Short key features of up to 80 characters each instead of five long bullets.
One-paragraph description of at least 150 words, the way Walmart shows it.
A+ modules move to Brand Highlights when the client owns the brand.
The tiles are now dressed in limestone and morning light. Walmart allows no test or performance claims on images, so two headlines change: 03 reads '18K gold vermeil, in section.' instead of '…measured in microns.', 06 the instruction 'Press the lever toward the hinge.' instead of 'A lever you can press with a thumbnail.'; the layer column, 'Not solid gold' and 'Adult jewelry, not a toy…' stay word for word. Walmart lists jewelry with silver and a sapphire only after its AML team approves the seller; the stone's and the piece's weight, the country and the stone report are the client's data, still blank fields.

Product description

Corund One Stone is a pendant necklace with one round laboratory-grown blue sapphire, 6.5 mm, in a smooth full bezel with an open back and a fixed hidden bail, on a 1.2 mm cable chain with soldered links and a 12 x 6 mm lobster clasp with a lever you can press with a thumbnail. The bezel is 8.3 mm across, 3.7 mm deep with the stone; the round window in its back is about 3.8 mm. Metal: 925 sterling silver plated with 18K gold, 2.5 microns minimum (gold vermeil). Not solid gold. Under the 18K gold layer: a palladium barrier. The gold layer is measured by XRF per lot. Stone: laboratory-grown sapphire, 6.5 mm; not a mined stone. It is corundum, aluminum oxide, Mohs 9, grown as a crystal and then cut. Its report number is on the label card. Length: 18 in (46 cm) plus a 2 in (5 cm) extender, measured end to end including the clasp. Also sold as 16 in + 2 in extender (41 + 5 cm). Quality mark: stamped 925 with the maker's mark on the back of the bail. Care: put it on last and take it off first; remove before swimming, showering, exercise and sleep; keep away from perfume, lotion, sweat and household chemicals; wipe with a soft dry cloth after wearing and store in the pouch. Gold plating and vermeil wear thin with time and use; replating is a normal service. When it dulls: thirty seconds with the plain cloth. Not on vermeil: silver dip, cloths with polishing compound, toothpaste, baking soda or ultrasonic baths; they take the gold layer off with the tarnish. If the gold layer wears thin, what shows is the 925 sterling silver core. A knock on a hard edge can still chip any cut stone. In the box: a slide box with a 50 mm ruler on the tray, a cotton pouch, the label card, a metal card, a care card, a plain cloth with no polishing compound and an anti-tarnish strip. No price inside. Adult jewelry, not a toy. Contains small parts: keep away from children.

Own store

The product page on the brand's own store, whole and in its style: gallery, buy box, ritual, ingredients, the line, questions and the brand story.

What's included

The first image is a clean pack shot with no text, so the product qualifies for Google Shopping.
On phones the add-to-cart button stays under the thumb.
Gallery at 2048 × 2048, the size Shopify recommends; page sections are standard Shopify store blocks.
Wide banner frames come from the same scenes; no new shoot needed.
The store page speaks the listing's language: pale limestone, warm graphite, Libre Caslon Display and Manrope, no gradients and no banner veil.

A live page inside the frame: scroll it, open the questions and the gallery. Checkout does nothing.

TikTok Shop

The same product for TikTok Shop, where people buy straight from the feed. The rules are different, so the listing is rebuilt.

What changed from Amazon

TikTok Shop allows no added text on any image: nine clean frames instead of infographics, the main one on white.
Product name on the beauty formula: brand, category, benefit, skin type, size.
The description must carry ingredients, directions and a patch test note.
People in the photos are AI-generated, and the description says so, as TikTok requires.
A 9:16 video under 5 MB for organic posts. A shoppable video on TikTok needs live footage, and we tell the client so.
Nine clean squares with no added text: the pendant, the back stamped 925, the whole necklace, the clasp with its tag and the box lie on the same limestone as the listing's tiles; the neck, the fingertip and the hands on the clasp are the people frames. Jewelry on TikTok Shop needs category qualification first: a lab report on the gold no older than a year, a GIA, IGI, AGS or AGL certificate for the stone and the country of origin on the piece or the packaging, still the client's data. 'Laboratory-grown' stands before every 'sapphire' and the metal is named in FTC terms.

Demonstration: the product card and the video built from the TikTok Shop files. Generic layout.
