Topaz Lots

Topaz is a silicate mineral of aluminium and fluorine with the chemical formula Al₂SiO₄(F, OH)₂. It is used as a gemstone in jewelry and other adornments. The name topaz was first applied to the mineral now known by that name in 1737.

Topaz comes in a range of colors, including yellow, blue, pink, green, and colorless. Its color is caused by the presence of impurities or defects in the crystal structure. For example, yellow and pink topaz are often colored by traces of iron, while blue topaz is created through a process of irradiation and heat treatment of colorless or pale yellow topaz.
