Sodalite (Hackmanite) (tenebrescent) (rare)

Item Description

This is one of only a handful of Hackmanite gems that I've seen from Burma, they are amazingly difficult to find, and much rarer than their Afghani counterparts. 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 UV Light. This stone is tenebrescent and also shows a good fluorescence under UV light. The stone fluoresces a pink under LW light. It will turn a PURPLE color after being exposed to prolonged UV light and then will return to a bluish color after being exposed to prolonged daylight (tenebresence). This process is 100% repeatable and in no way hurts the stone. This gem has a "Cushion" cut and is somewhat translucent for all intents and purposes. This material is retailing for HIGH numbers now across the board, and you simply can't get your hands of the Burmese material. I saw one of these stones offered at the Tucson Show last year for $900 per carat for reference, but this stone is not as high of quality.
