Fancy Color Research Foundation (FCRF) is a non-profit organization that promotes the transparency and fair trade of fancy colored diamonds. The foundation was initiated in 2005 and officially inaugurated in November 2014. The FCRF conducts research on all aspects of fancy color diamonds and publishes quarterly updates of the Fancy Color Diamond Index (FCDI), which illustrates price changes in the market behavior of natural fancy color pink, blue and yellow diamonds in various sizes and saturation levels. The FCDI tracks pricing behavior over time and does not publish any actual prices.
