The mineral Topaz, also known under the misleading trade names Finder’s Diamond, Killiecrankie Diamond, Mogok Diamond, Saxon Diamond and Slave Diamond[6], is a common island silicate with the chemical composition Al2[6][(F,OH)2|SiO4]. The fluorine (F) and hydroxide ions (OH) in the round brackets can substitute for each other 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.[7]
Topaz crystallizes in the orthorhombic crystal system and typically develops well-formed and partly very flat crystals with short- to long-prismatic or columnar habit and glassy luster on the surfaces. In pure form it is colorless and transparent. Due to multiple light refractions caused by lattice defects or polycrystalline nature it can also appear white and take on a yellow, pinkish, brownish-red, violet, light blue and pale green color with decreased transparency.
With a Mohs hardness of 8, Topaz is a hard mineral and serves as a reference on the Mohs scale up to 10 (Diamond). Similar to Diamond, it is also brittle and, based on the basal plane (001), very easily cleaves along perfectly smooth fracture surfaces, which is often already hinted by cleavage cracks in the stone. Irregularly broken Topazes show irregular to weakly conchoidal (shell-like) fracture surfaces.
