Dianco is privileged to be a De Beers Group Sightholder. Our sales team travels to Botswana about ten times a year to purchase and inspect rough diamonds directly sourced from their mines in Canada, Botswana, Namibia, and South Africa. As a Sightholder, we can offer our customers a consistent and reliable supply of diamonds.

Dianco is accredited as an Alrosa Alliance Member. Alrosa is known for having the largest rough diamond reserve in the world. As an Alliance Member, we have direct access and receive a consistent supply of rough diamonds that are produced in their mines in Russia.
