Description from the seller
Blue Topaz Ring / new
Set in 925 sterling silver
3.68 g / 18.4 ct
Ring size
U 58 - 59 (is exactly in between)

Inner diameter: 18.65 mm
Brand new and unworn
The mineral Topaz is a nesosilicate with the chemical composition Al2[6][(F,OH)2|SiO4].[3] The fluorine (F) and hydroxide ions (OH) indicated in the parentheses can substitute for one another in the formula (substitution, diadochy), but always in the same proportion relative to the other constituents of the mineral. An F-free OH-analog is known as a synthetic compound.[7]
Topaz crystallizes in the orthorhombic crystal system and usually forms well-developed crystals that are sometimes quite broad, with short- to long-prismatic or columnar habits and a glass-like luster on the surfaces. In pure form, it is colorless and transparent. However, due to multiple light refractions caused by lattice defects or polycrystalline structure, it can also appear white and may take on yellow, pinkish-red to brownish-red, violet, light blue, and light green colors due to impurities, with transparency decreasing accordingly.
