New and unworn
The mineral topaz is an island silicate with the chemical composition Al2[6][(F,OH)2|SiO4]. The fluorine (F) and hydroxide (OH) ions indicated in the round brackets can substitute for one another in the formula (substitution, diadochy), but always in the same proportion to the other components of the mineral. An F-free OH-analogue is known as a synthetic compound.
Topaz crystallizes in the orthorhombic crystal system and typically forms well-developed and sometimes very plane-rich crystals with short- to long-prismatic or columnar habit and a glassy luster on the surfaces. In pure form it is colorless and transparent. Due to multiple light refractions caused by lattice defects or polycrystalline growth, it can also appear white and, with impurities, take on a yellow, pinkish to reddish-brown, violet, light blue, and light green color, with the transparency accordingly decreasing.
