For buyers
Natural diamond supply, matched to your criteria
CaratBid connects verified diamond buyers with private sellers across Europe. Set your purchasing criteria once and receive only the opportunities that fit.
Why buyers use CaratBid
Direct private supply
Access diamonds from private sellers rather than competing only on trade platforms.
Criteria-based matching
Choose shapes, carat ranges, colour, clarity, certification and regions. You only see relevant stones.
Confidential offers
Your offer is visible to the seller and to CaratBid — never to other buyers.
Structured information
Certificate details, photographs and grading captured consistently for every submission.
Direct introduction
When a seller accepts, CaratBid introduces you so inspection and settlement can be arranged.
No wasted enquiries
Sellers submit deliberately, with ownership confirmed at the point of submission.
