Blue Beryl or Aquamarine is a blue or blue-green variety of Beryl, a beryllium aluminium silicate mineral.

  

History records it’s first use in Greece between 300 and 500 B.C. It’s name, derived from the Latin meaning ‘water of the sea’ is an apt description of the colour and clarity of fine Aquamarine crystals.


It has been mined in Brazil, Pakistan, Afghanistan, Australia, Africa and the United States.


  

The Mica group of sheet silicate minerals includes several closely related materials having nearly perfect basal cleavage. All are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical composition. The nearly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms.


The word mica is derived from the Latin word mica, meaning a crumb, and probably influenced by micare, to glitter.
