Hackmanite is a rare mineral that belongs to the halide mineral group. It is a translucent to transparent mineral with a vitreous luster and typically exhibits a yellow to greenish-yellow color.
Hackmanite is known for its unique property called tenebrescence. This means that the mineral can display a different color under various lighting conditions. When exposed to shortwave ultraviolet (UV) light, Hackmanite can exhibit a deep purple or violet color. However, when the UV light is removed, it gradually fades back to its original yellow or greenish-yellow color. This phenomenon is known as reversible photochromism.
The tenebrescent behavior of Hackmanite is caused by the presence of trace amounts of sulfur (S) within the crystal structure. The sulfur ions can trap electrons, which are released when exposed to UV light, resulting in the purple color. This responsive characteristic has made Hackmanite a popular material in jewelry, especially when cut into gemstones.
Hackmanite was first discovered in Greenland in 1896 and was named after Axel Hackman, a Finnish mineralogist who extensively studied the mineral. It is also found in other locations around the world, including Afghanistan, Canada, Russia, and the United States.
In addition to its use in jewelry, Hackmanite is also of scientific interest due to its ability to store luminescent energy and its potential applications in technologies such as optical data storage and fluorescent lighting.

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