This tourmaline is a beautiful rich blue-green color–green with a blue secondary. Completely natural and untreated, this tourmaline comes from recent mining work in Nigeria. It is very clean, with just a few tiny trichyte inclusions, only visible with a 10x loupe. The high clarity makes this a striking gemstone in the hand, glittering and quite brilliant for the depth of color.
I faceted this gem in a modified version of my custom “Aurora” brilliant square design. The resulting gemstone is extremely bright and flashy, and has excellent off-axis performance. The gem weighs 5.79 carats and measures 9.5 x 8.2 mm. It would make a beautiful center stone for a pendant or ring.
