Sodalite (var: Hackmanite) (tenebrescent) (rare)

Item Description

We've only had a few really top quality Hackmanite (the gem variety of the mineral Sodalite) gems to offer in the auctions. The particular stone is one of the best and biggest gems that we've ever had in our inventory, let alone in the auctions. The best gem quality Hackmanite stones come from Afghanistan, but we haven't seen anything of significance in several years. They are amazingly difficult to find on the market now. Sodalite is a very durable stone and that's why it is so popular among dealers and collectors alike, because it's rare and can still be worn in jewelry. The Afghani Hackmanite is tenebrescent which is the process by which a mineral changes daylight color after being exposed to ultra-violet light. This particular stone shows a good fluorescence under both LW and SW UV light, which is what causes the tenebresence. The stone fluoresces an electric yellow hue under LW UV light and a softer greenish-yellow hue in SW UV light. You can see a noteworthy phosphorescence in photos that will actually turn the stone a STRONGER PURPLE color in daylight after being exposed to prolonged UV light, this is tenebrescence. It will then return to its original light purple color after being exposed to prolonged daylight. This process is 100% repeatable and in no way hurts the stone. This gem has a "Brilliant Oval" cut and is very very slightly included which is great for the material as most of them have serious inclusions. It's nearly impossible to find completely clean stones unless they are exceptionally small. This material is retailing for HIGH numbers now across the board, and you simply can't get your hands on gems with this kind of clarity. This stone is priced at $2,540.00 retail in our inventory.
