Summary

Description
English: Sodalite
Locality: Afghanistan (Locality at mindat.org)
Size: thumbnail, 9.8 x 8.2 mm ; 2.04 carats
Sodalite (var
Hackmanite)
Since this new find of Sodalite hit the market a few years ago, I have been quite impressed with the amount of relatively clean stones out there. Sodalite is a very durable stone and that's why it is so popular among dealers and collectors alike. The gem variety of Sodalite is Hackmanite and it is tenebrescent which is the process by which a mineral changes daylight color after being exposed to SW Light. This stone is very tenebrescent and also fluoresces well under LW/SW UV light. The stone fluoresces orange under LW and light orange under SW. The Hackmanite will turn a slight lavender color after being exposed to prolonged SW light and then will return to normal color. This process is 100% repeatable and in no way hurts the stone. This gem has a very very light lilac color (nearly colorless), but it is certainly a larger stone and one of the cleanest pieces in this size range that I have seen. The stone is virtually eye clean, which is very difficult to find in this material. Make no mistake, this is a significant collectors gem. This material is retailing for HIGH numbers now across the board!
