We are partnered with a number of boutiques, ethical mining operations that have access to high-quality loose diamonds for your collections or investments.

Ethically sourced
Bosco Diamonds has a zero-tolerance policy toward the conflict diamond trade and because we are so actively involved in the sourcing and polishing of our goods, we have the opportunity to proudly promote and enforce the standards established by the Kimberley Process, on a ‘grassroots’ level. We consider this to be the single most important attribute of the business.

GIA certified
All Bosco Diamonds inventory is certified by the world-leading gemological laboratory, known as the Gemological Institute of America (GIA).

GIA tests every material submitted to determine whether it is a natural diamond or synthetic diamond, and discloses any known treatments discovered during analysis.
