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.

Item was not as described in fact, it was totally different. Seller offered refund for the return of the gem however it would cost me more to send it back then it was worth it.

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.
