A CGEMX inspection, credited back if you buy, or the CGEMX viewing facility, free.
Above the limits
Up to US$10,000 a purchase and US$15,000 in any 30 days without an ID check. Above that, a passport and a selfie, checked by CGEMX.
The ✓ Verified store badge
Only Verified stores can sell. The badge is free: CGEMX checks your company documents and your standing in the trade. Open an account, fill in your business details in Settings and apply there. Or tell us about your store below and we will guide you through it. This is what to have ready.
Business identity
Who we are dealing with, and where you are registered.
Identity of principals
Required for standard anti-money-laundering checks.
Trade standing
Evidence that you are an established participant in the trade.
The stones you intend to list
You don't need final inventory, but we need to know what you'd bring.
Settlement details
Collected once you are approved, not at application.
Vault preferences
Where you would like stones held, and how you'd send them.
