White Topaz

Topaz is a mineral of the silicate class, being an aluminosilicate of fluorine and aluminium hydroxide.

Here are some technical details about natural topaz:

• • Chemical composition: The chemical formula of topaz is Al2SiO4(F,OH)2, indicating the presence of aluminium, silicon, fluorine and aluminium hydroxide in its structure.
  • Hardness: Topaz is known for its hardness.
  • On the Mohs scale, which measures the hardness of mineral materials, topaz ranks at 8, which is harder than most gemstones but less hard than diamond.
  • Color: Topaz can have a wide variety of colours, from colourless to shades of blue, yellow, pink, green, brown or even red.
  • This colour variation is due to impurities present in the crystal or certain treatments applied to the stone.
  • Transparency: Topaz can be transparent or translucent, depending on the degree of impurities and its crystalline structure.
  • Crystallization system: Topaz crystallises in the orthorhombic system, which means that it has a crystallisation system with three axes of equal length and right angles between them.
  • Cleavage:
  • Topaz has a perfect two-way cleavage, which means it can be easily split into parallel plates.
  • Density: The density of topaz generally varies between 3.4 and 3.6 g/cm2, which is a useful indicator for its identification. 8Origin
  • Natural topaz can be found in various regions of the world, including Brazil, Sri Lanka, Russia, Mexico, Pakistan, the United States and other countries.
