KORNERUPINE

Emerald has mesmerized gem lovers for millennia. Tsavorite has had us all hypnotized for half a century. And over the last few years, gemstone connoisseurs have gasped in wonder at the highly pleochroic green kornerupine found in Tanzania.

Unlike most kornerupine that comes in pale and not very appealing colors, the vibrant green hue of the stone from Tanzania is due to chromium and vanadium, and has no equivalent in the gem market. Is anything else needed to take your breath away? Well, this wonder gem has boron hidden inside it... in the same proportion as the “Hope diamond”.
