Terminated single Chrome Tourmaline crystal from a one time find at the Commander Mine in Tanzania. Chrome Tourmaline is a chromium and vanadium rich Dravite. The crystal is complete all around with deep emerald green coloration in the upper half and a more olive green in the lower half - I saw a large percentage of the find and can say this is the top quality for the find. Fantastic color and highly gemmy. Undamaged. From a spectacular pocket opened in 2016. Weighs 2.9 grams
