Description from the seller
Blue Topaz Ring / new

Inner diameter: 18.1 mm
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 shown in round brackets can substitute for each other in the formula (substitution, diadochy), but they always occur in the same proportion to the other components of the mineral. An F-free OH-analog is known as a synthetic compound.
Topaz crystallizes in the orthorhombic crystal system and usually forms well-developed and sometimes very plane-faced crystals with short- to long-prismatic or columnar habit and a vitreous luster on the surfaces. In pure form it is colorless and transparent. However, due to multiple light refractions from lattice defects or polycrystalline structure, it can appear white and, through impurities, take on yellow, pinkish to brownish-red, violet, light blue and light green colors, with transparency accordingly decreasing.
