DiamondMaster's "Bright List" from TROY DIAMOND REPORT® developed by Wayne D. Prentice, Graduate Gemologist and former Resident Gemology Instructor at the Gemological Institute of America (GIA), is the next generation global wholesale pricing guide that provides what Rapaport is missing!

Follow Wholesale Diamond Prices in 13 Mediums of Exchange and by 7C's!! The traditional 4C's: Cut Shape, Carat, Color, Clarity, plus "Cut Grade", "Cost" and "Change in Value" over last year and 5 years!! This App calculates % changes-in-value in your selected currency, Appreciation (or depreciation), which allows you to determine which "classifications" are maintaining best value in your local market. Quickly determine and compare each diamond's value in multiple FIAT currencies and exchange for Troy ounces of gold - the universal unit of utility!
