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.

Why are users outbidding themselves?
When a bid is placed, this is the maximum amount a person is willing to bid for the product. Our system will then automatically bid on behalf of the bidder, incrementally increasing the bid up to the maximum to maintain their position as the highest bidder.
When there is an icon indicating 'Automatic Bid', it means our system is actively placing bids for the bidder based on their maximum bid. This may appear as if bidders are outbidding themselves, but it's simply a result of the system updating the bid to reflect the bidders maximum limit.
