Privately-held India Bore Diamond Holdings said earlier this month that a number of diamonds mined within the L-Channel of its project display an extremely rare purple or violet natural fluorescence.

The company is focused on producing rare fancy colored diamonds. The company’s operations are in the Ellendale Diamond Field located in northern Western Australia

“Ellendale 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,” writes the company.

The company said 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.

“Violet or purple fluorescence is normally associated with blue diamonds, so the fluorescence of these IBDH diamonds is quite unusual”, said John Chapman of Perth-based Delta Diamond Laboratory.
