A gorgeous mint green Nigerian tourmaline in my custom “Helena” brilliant oval design, 8.78 carats.

1 in stock


This tourmaline is a beautiful mint green color–light 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 small trichyte inclusions, only one of which is visible with a loupe.  In the hand at normal viewing distance the gem appears completely clean and is very bright and scintillating.

I faceted this gem in my custom “Helena” brilliant oval design.  The resulting gemstone is extremely bright and flashy, and has excellent off-axis performance.  The gem weighs 8.78 carats and measures 13.7 x 11.6 x 9.0 mm. It would make a beautiful center stone for a pendant or ring.
