For Jewelers
Sell to buyers who read specifications.
The Karat Club is a curated network, not an open marketplace. Every partner is reviewed and manually approved, and every listing must meet The Karat Standard before it is published.
Curated demand
Buyers arrive expecting real weight, purity and construction — not a race to the lowest price.
One data standard
Structured specifications replace vague listings, which reduces returns and disputes.
Verification layer
Eligible pieces can be routed to The Karat Club for physical verification.
Exchange ecosystem
Pieces sold through the network can enter The Exchange later, which supports resale confidence.
What we require
Every listing, fully specified.
A listing is not published until each of these is present. This is the single non-negotiable condition of network membership.

The Karat Club reviews identity, product quality and data capability by hand.
03

Publish
Each listing is checked against The Karat Standard before it appears.
05
Monitor
Partners are monitored on data accuracy and can be paused or suspended.
Verified Partner describes the seller business only. It is not an appraisal, certification or guarantee of any individual piece.
