About The FCRF 

Passion. Rarity. Value. Knowledge. Standardization. Integrity. 

The Fancy Color Research Foundation (FCRF) seeks to broaden knowledge and cultivate the appreciation and fair trade of fancy color diamonds. We provide timely data, research, tools, and services to leading diamond companies and industry professionals, empowering them to optimize their business abilities in the fancy color diamond arena. As a non-trade organization, we reinvest earnings into further research or donate them to the Make-a-Wish Foundation, fulfilling the dreams of critically ill children.
