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.

Pourquoi les utilisateurs se surenchérissent-ils ?
Lorsqu'une enchère est placée, il s'agit du montant maximum qu'une personne est prête à enchérir pour le produit. Notre système enchérira alors automatiquement au nom de l'enchérisseur, augmentant progressivement l'enchère jusqu'au maximum pour maintenir sa position de meilleur enchérisseur.
Lorsqu'une icône indiquant « Enchère automatique » apparaît, cela signifie que notre système place activement des enchères pour l'enchérisseur en fonction de son enchère maximale. Cela peut donner l'impression que les enchérisseurs se surenchérissent, mais c'est simplement le résultat de la mise à jour de l'enchère par le système pour refléter la limite maximale des enchérisseurs.
