How it works
From first search to a trusted deal
Three steps, and both sides have already been checked before you speak.
- Step 1
Join and get verified
Create a free account. Premium and Exclusive access follows a short identity check.
- Step 2
Browse and inquire
Filter by variety, origin, weight and treatment, or describe the stone you want. Send an inquiry to the seller.
- Step 3
Agree the deal
The seller replies through the Hub. You agree terms with a seller we have already verified.
Managed trust
We check both sides, so you do not have to
We only make the introduction once we are satisfied that the buyer and the seller are who they say they are.
