An independent study of IBDH diamonds by Perth-based Delta Diamond Laboratory has revealed that a number of diamonds mined within the L-Channel at Ellendate display an extremely rare purple or violet fluorescence. Ellendate fancy yellow diamonds command a premium in the market and are regarded by many world diamantaires as among the highest quality fancy yellow diamond production in the world. Fluorescence occurs in about 30% of natural diamonds and more than 95% of these fluoresce blue, with yellow and green representing just a few percent.
