Independently Certified

We feature diamonds from some of the most highly respected independent grading labs in the world such as the Gemological Institute of America (GIA), HRD, IGI to name a few.

Conflict Free

As a member of the wholesale diamond trade, Gem Stone King adheres to the international Kimberly Process Statement which requires us to obtain invoices from our suppliers for every purchase we make that states: “The diamonds herein invoiced have been purchased from legitimate sources not involved in funding conflict and in compliance with United Nations resolutions. The seller hereby guarantees that these diamonds are conflict free, based on personal knowledge and/or written guarantees provided by the supplier of these diamonds.”

Guaranteed Available

The certified diamonds displayed here for your selection are part of a real-time international diamond trading exchange. This allows you access to more stones than most jewelers have access to!

In the event a diamond is no longer available, Gem Stone King will quickly assist you in identifying an alternate diamond of similar quality and price.
