Bought through CGEMX, not from a stranger

The trade still runs on discretion. CGEMX stands in the middle, so you never have to take anyone at their word.

Open an account
01

Checked against its report

Every stone is matched to the report of the laboratory that issued it before it is listed. Enhancement is stated on every listing.

02

You pay CGEMX

You pay by card, to CGEMX, and you pay the price you see. The seller pays the 3.95% fee and the card fee, and is paid by CGEMX once the sale completes.

03

See it first

Book a CGEMX inspection: a gemmologist examines it for you, and the fee is credited back if you buy. Or view it yourself at the CGEMX viewing facility, free.

04

Offers that cost nothing

An offer is a hold on your card for up to seven days. It is charged only if the seller accepts, and released if not.

05

Verified stores only

Only stores CGEMX has checked, on their company documents and their standing in the trade, can sell. Stars come only from completed sales.

06

Anonymous on both sides

Neither side sees the other’s name. Ask the seller anything in the chat; contact details are kept out, so the deal stays protected inside CGEMX.

OPENS NEXT · Vault Trade

After Stock Trade, Vault Trade opens: only the finest untreated stones, certified by GRS, SSEF, Gübelin or AGL, held in insured custody and traded on private offers while the stone never moves. 32 are shown as a preview.
