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.

Waarom overbieden gebruikers zichzelf?
Wanneer een bod wordt geplaatst, is dit het maximale bedrag dat een persoon bereid is te bieden voor het product. Ons systeem zal dan automatisch bieden namens de bieder, waarbij het bod stapsgewijs wordt verhoogd tot het maximum om hun positie als hoogste bieder te behouden.
Wanneer er een pictogram is dat 'Automatisch bod' aangeeft, betekent dit dat ons systeem actief biedingen plaatst voor de bieder op basis van hun maximale bod. Dit kan lijken alsof bieders zichzelf overbieden, maar het is gewoon een resultaat van het systeem dat het bod bijwerkt om de maximale limiet van de bieder weer te geven.
