Ring Aquamarine / new
Set in 925 sterling silver
Weight: 1.24 g / 6.2 ct

Aquamarine is the blue variety of the silicate mineral beryl and crystallizes in the hexagonal crystal system with the chemical composition Be3Al2[Si6O18].
Its blue color is due to trace amounts of iron ions in two- and three-valent states (Fe2+ and Fe3+) at various lattice positions. As an allochromatic (foreign-colored) mineral, the streak color of aquamarine is therefore always white. The color named after the gemstone is a vivid greenish-blue, but pale blue to dark blue beryls are also referred to as aquamarine.
Due to its high Mohs hardness of 7.5 to 8 and its often well-formed, clear crystals, aquamarine is predominantly processed into gemstones for jewelry.
