5.45CT Natural Katlang Topaz stone
Weight:(5.45)CT
Stone:(Topaz)
Origin:( Pakistan From Katlang)
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.

Why are users outbidding themselves?
When a bid is placed, this is the maximum amount a user is willing to bid for the product. Our system will then automatically bid on that users behalf, incrementally increasing the bid to maintain their position as the highest bidder, up to the specified maximum.
When there is an icon indicating 'Auto Bid,' it means our system is actively placing bids for the user based on their maximum bid. This may appear as if users are outbidding themselves, but it's simply a result of the system updating the bid to reflect the users maximum limit.
