Rapaport Auctions is an international diamond and jewelry auction platform. It is known for organizing monthly sealed-bid auctions of melee and single polished diamonds.
Overview
Rapaport Auctions was founded as a subsidiary of Rapaport Group, by Martin Rapaport in 1976.[1][2][3]
It conducts diamond melee and single-stone auctions.[4][5] Melee auctions consist of parcels of small, uncertified polished diamonds typically under 0.2 carats each, sold in bulk lots with a total weight ranging from 30 to 500 carats. Many melee lots consist of recycled diamonds.[6][7][8] Single-stone auctions involve individual loose diamonds ranging from 0.30 to over 5 carats. Both certified and uncertified diamonds are auctioned and disclosed as such to the bidder.[9][10][11]
The service uses a sealed-bid, silent auction format with multi-day viewing sessions that allow buyers to inspect lots before placing bids. Participants are usually wholesalers, retailers, diamond dealers and pawnbrokers.[12] Auctions are conducted in New York, Las Vegas, Antwerp, Ramat Gan, Dubai, Mumbai, Surat, and Hong Kong.[13][14][15][16][17]
In December 2017, it handled the sale of the 709-carat Peace Diamond for Sierra Leone.[18][19][20]
