DiamondMaster vs GemGuide Pricing

ONE DIAMOND. TWENTY-SEVEN WAYS TO MEASURE ITS VALUE. What changes when you measure a diamond in gold instead of dollars? Or Bitcoin instead of Swiss francs? DiamondMaster helps diamond professionals, gemologists, appraisers, buyers and traders explore wholesale reference values for Mined-Natural and Grown-Created diamonds. Compare classifications, adjust your pricing basis, and see how a different exchange unit changes the picture. Developed by Wayne D. Prentice, Graduate Gemologist and former GIA Resident Gemology Instructor, DiamondMaster brings gemological knowledge and the BrightList wholesale reference guide together on iPhone and iPad.

By liberating diamond valuation from the traditional US Dollar peg, the 'Bright List' normalizes a diamond's intrinsic scarcity, extraction costs, and luxury premium across 27 distinct economic units. Whether you are tracking a gem by its 4 C’s or analyzing macro liquidity shifts, our advanced dual-period tracking over 1- and 5-year intervals reveals the true reality of wealth: letting you see instantly whether your diamond is genuinely appreciating, or if your chosen currency is losing its purchasing power.
