Everyone buys diamonds — few show you the difference
Shopfronts advertising "we buy diamonds" all quote from their own position. CaratBid shows your stone to verified buyers together, so the difference between their offers is visible rather than hidden.
- Several buying houses on one stone
- Price spread visible immediately
- Free to submit and free to decline
