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.
