Discovered in Greenland in the late 1890’s, hackmanite is named for Finnish geologist Victor Hackman. It is a rare occurrence to find gem-grade hackmanite; at best, most crystals are translucent. Hackmanite is the light pink to pale violet variety of sodalite. It is a particularly unusual gem because it exhibits a special optical property known as “tenebrescence,” a type of reversible photochromism. This feature allows the gems to temporarily change color when exposed to different light forms. While hackmanite gems are usually pink to violet, the color quickly fades to gray or greenish-white in sunlight, and will slowly return to the original color after changing the light. Its tenebrescent property makes hackmanite a prized mineral for collectors.

The seller never sends out the item. Every time I asked them when I could get a tracking number for my order, they said they were busy and would send it right away on that day. This kind of situation repeated several times. Finally got a refund on paypal.
