SOURCING ONLY THE BEST
Recognized as a De Beers Group Sightholder, Alrosa Alliance Member and Rio Tinto Select Diamantaire for the world's largest mines, Dianco’s diamonds are hand-selected and polished to perfection in-house. As a sightholder diamond trading company, we promise you the best of the best. Always.
DIAMOND SIGHTHOLDERS OF THE
DE BEERS GROUP
Dianco has been a Sightholder of De Beers Group since 2012. As one of only a handful of companies that comply with their requirements, we are privileged to be selected to be part of the De Beers Group Diamond Trading Company sightholder list. De Beers controls the second-largest distribution of mined, rough diamonds around the world and 90% of their rough diamonds that come from their mined operations in Canada, South Africa, Namibia, and Botswana are sold to the members on their diamond sightholder list.
So how do sightholders buy diamonds? As part of the DTC diamond sightholder list, we receive a consistent supply of the De Beers diamonds and about 10 times a year, our team heads over to Botswana to inspect the goods before we decide what to purchase. All of the De Beers mines are certified by the Responsible Jewellery Council Code of Practices and are compliant with the De Beers Group Best Practice Principles giving us the ability to confidently give our customers assurance on the integrity and authenticity of the diamonds.
SELECT DIAMANTAIRE
RIO TINTO
Since 1985, Dianco has had the honor of being a part of the Rio Tinto Select Diamantaire family. To make it to their elite group, a company has to be recognized for their unmatched skill in diamond trading, cutting, polishing and marketing. The selected company must also promise to consistently comply with the Rio Tinto Diamonds Chain of Custody.
The Rio Tinto diamond mines are the third-largest producers of mined, rough diamonds across the globe. As a Select Diamantaire, we receive a regular and uniform supply of rough diamonds from their responsibly-mined Diavik Diamond Mine in Canada.
ALLIANCE MEMBER
ALROSA
Alrosa is the largest supplier of mined, rough diamonds in the world. Only a handful of global companies are selected to be an Alrosa Alliance Member. We have been fortunate to be picked as members of this esteemed group since 2009 and, as Alrosa Sightholders, we receive a steady supply of rough diamonds from their mines in Russia.
Companies that are part of the Alrosa Alliance must comply with the requirements of the Kimberley Process and the System of Warranties of the World Diamond Council. Moreover, all Alliance member companies must maintain a certain standard of business practices and corporate ethics, have the ability to add value to the diamonds, and have a successful distribution network with significant geographical exposure. Dianco is proud to be recognized as an Alrosa Alliance Member.
THANKS TO OUR ALLEGIANCE WITH THE BEST MINING COMPANIES AROUND THE WORLD.
As diamond sightholders in India and across the globe, we have the widest selection of the most top-quality diamonds that fit your every need.
