Billiton Diamonds DMCC sells its rough diamonds through a “Highest Losing Bid” award logic to competitive companies.

We invite the companies to participate in the auctions based on the availability of the goods and its type, providing full end to end data pack for assortments and quality analysis.

Future Invitations will depend on the participating customers engagment with our diamond viewing events and their performance in the past auctions.

The expression of interest and the regular legal (AML) documentation is one criteria to do business with us.

Interested parties can fill out the Billiton Diamond Expression of Interest Form and email it to sales@billitondiamondauctions.com
