Listing a stone: the form, the checks, and going live

How to add a stone and put it on the shop — identity, lab report, origin and treatment, price band, delivery terms and documents — and what the buyer then sees.

Illustration

Who it's for: Dealers and jewelry stores.
What you need ready: A photo of the stone — macro, on a neutral background. A phone photo works.
Its weight, colour, shape, origin and treatment.
The lab report number and date, if the stone has a report.
Dealers: an invoice, a consignment agreement or other proof of your right to sell, as a PDF or a photo.
How long it takes: A few minutes per stone.
What it costs: Listing is free. When the stone sells: no commission while we launch under $10,000, 5% from $10,000.

Open the form

Press Add a stone on your dashboard or in your inventory. The form has four blocks.

A · Identity

The Add a stone form: the stone's identity and its lab report — ① the stone's facts, ② the photo, ③ the laboratory, ④ the report number — the report is optional

Stone type ①, Weight, carats, Color (lab terminology), Shape, and if you have them Cut and Dimensions, mm.

Photo (macro, neutral background) ② — on a phone it opens the camera. A lot without a photo shows a "photo pending" mark and sells less well.

B · Lab report (optional)

Laboratory ③, Report number ④ and Report date. What you put here decides what the buyer is told:

Left empty: the lot goes live as “Seller-declared”. Your business verification is what stands behind it.
Filled in: the lot goes live at once, and the desk cross-checks the report against the laboratory's own records while it is selling. When the check clears, the lot gains its tick (✔) and you get a letter.

A report needs both: “A report needs both a laboratory and its number — or leave both empty and list as seller-declared.”

The four levels of a check

Seller-declared
Only the seller is verified. The facts and photos are the seller's own.
Card
○ Stone as declared by the seller
The lot
Seller-declared
Public page
none
Paper cross-checked
The report was confirmed with the lab that issued it. Nobody on our side has seen the stone.

In custody — passport reflects title
The stone is in a vault. While it stays there, its passport matches this stone and this owner.

Each level adds one fact to the one below. At level 0 the seller is still verified — only the stone rests on their word. A listing that shows a lab certificate stays at level 0: the paper is the seller's, not our check.

Good to know ·Add the report here, when you add the stone. The cabinet has no button to attach one to a stone later: “A report that comes later goes to our desk: email it to” the address on the form, with the stone's ID from your inventory. The desk cross-checks it against the laboratory's own records, and a letter tells you the outcome.

C · Origin & treatment

Origin country and Treatment.

Listing

The Add a stone form: price, delivery terms and documents — ① Asking price, USD, ② your delivery terms, ③ the documents for this stone, ④ Publish to the shop

1.
Asking price, USD ①. The tier follows the price: under $10,000 is T0, from $10,000 to $30,000 T1, from $30,000 T2. A T2 lot needs the stone in the vault first, so the form refuses a price from $30,000 for a new stone — list it below $30,000, or ask the desk to arrange custody intake.
2.
Your delivery terms ②: insured delivery included in your price, or charged to the buyer. See Delivery terms.
3.
The documents for this stone ③.
- Dealer: Document type — Purchase invoice (own stock), Consignment agreement or Other proof of right to sell — and File (PDF or photo). Both are required.
- Jewelry store: “Origin of your inventory (required)”, with a file if you have one. See Jewelry stores.

Publish

The button ④ follows your business verification.

Your business is verified: press Publish to the shop. The lot is on the shop at once — nobody reviews it first. Your inventory says “Live on the shop as” and the lot's label, “Seller-declared” for a new stone — and, if you gave a report, that it is with the desk.
Your verification is still in review: press Save as a draft. The lot waits for the approval: “Saved as a draft — it goes on the shop in one click the moment your business verification (KYB) is approved.”

What the buyer sees

Your lot shows “Seller verified”, the stone's line (see Reading a lot) and what the buyer can add. The buyer sees your price, and pays the buyer's premium and the settlement fee on top of it — you receive your price, less any commission, plus your delivery charge if you set one.

After it is live

If the desk has a question about the report, your inventory shows “The desk asks:” with it. Reply to the desk's letter.
If the report is confirmed, the stamp and the card's line change, and a letter tells you.
If it cannot be confirmed, the inventory shows “Not confirmed:” with the reason. The lot stays on the shop as Seller-declared.

List a stone you already hold

A stone in your inventory that is off the shop has List for sale. The page asks for the price, the delivery terms and the documents again; press Publish to the shop (Save as a draft while your verification is in review). With your business verified, it goes on the shop straight away, and your inventory names the label it carries — a stone the desk has already checked keeps its tick. A stone already in custody can be listed from $30,000 and sells from the vault, without travelling.

Take a lot off the shop

Withdraw in your inventory. Not while a buyer's order holds the stone: “A buyer has ordered this stone — the lot stays until their order ends.”

Common problems

“Check the required fields”

“Check the required fields — type, weight, color, shape, origin and price.”

The form refused my price

From $30,000 a stone must be in the vault first. List it below that, or write to the desk about custody intake.

“The documents block is required”

A dealer's lot needs a document type and a file: “The documents block is required to list the stone.”
