5.45CT Natural Katlang Topaz stone
Weight:(5.45)CT
Stone:(Topaz)
Origin:( Pakistan From Katlang)
Treatment: Natural Topaz( Not radiated)
Topaz is a silicate mineral made of aluminum and fluorine with the chemical formula Al2SiO4(F, OH)2. It is used as a gemstone in jewelry and other adornments. Common topaz in its natural state is colorless, though trace element impurities can make it pale blue or golden brown to yellow-orange.[7] Topaz is often treated with heat or radiation to make it a deep blue, reddish-orange, pale green, pink, or purple.
Topaz is a nesosilicate mineral, and more specifically, an aluminosilicate mineral.[9] It is one of the hardest naturally occurring minerals and has a relatively low index of refraction. It has the orthorhombic crystal system and a dipyramidial crystal class.[10]
It occurs in many places in the world. Some of the most popular places where topaz is sourced are Brazil and Russia.[7] Topaz is often mined in open pit or alluvial settings.

Pourquoi les utilisateurs se surenchérissent-ils ?
Lorsqu'une enchère est placée, il s'agit du montant maximum qu'un utilisateur est prêt à enchérir pour le produit. Notre système enchérira ensuite automatiquement au nom de cet utilisateur, augmentant progressivement l'enchère pour maintenir sa position d'enchérisseur le plus élevé, jusqu'au maximum spécifié.
Lorsqu'il y a une icône indiquant "Enchère automatique", cela signifie que notre système place activement des enchères pour l'utilisateur en fonction de son enchère maximale. Cela peut donner l'impression que les utilisateurs surenchérissent eux-mêmes, mais c'est simplement le résultat de la mise à jour de l'enchère par le système pour refléter la limite maximale des utilisateurs.
