Mineral Species: Beryl var. Goshenite

Chemical Formula: Be3Al2Si6O18

Chemical Name: Beryllium Aluminium Silicate

Mineral Class: Cyclosilicate

Mineral Notes: Beryl is not particulalry well known by the general public although its coloured varieties are instantly recognised as the gem stones Emerald and Aquamarine. The latter is a popular stone but does not command nearly as high a price as its green relative. Uncut aquamarines are common but relatively expensive, as would be expected of crystalline gemstone specimens. Goshenite is a rare colourless variety.
