About Us

Ethically Sourced - Mine Direct


Detroit Diamond Company ensures all rough diamonds are ethically sourced, following the Kimberly Process Certification Scheme (KPCS).  All diamonds are conflict free and are in compliance with United Nations Resolutions. 

Identifying Quality


We allocate parcels according to each client's customer base. When in the field, each stone undergoes various testing, ranging from stress, color, fluorescence and optimal cut outcomes with state of the art technology and mapping.

The Delivery


Detroit Diamond Company can either provide you rough diamonds to suit your own cutting strategy, or provide you with a finished and complete stone. Our cutters have spent over 30 years perfecting their craft, located in the United States and Belgium.
