⤱ Beryl ⤱

Beryl is a beryllium silicate, formula Be3Al2Si6O18, and provides us with a number of gem varieties such as emerald (green), aquamarine (blue) and morganite (pink). It often occurs as prismatic crystals embedded in the surrounding matrix and can be difficult to extract without damage.

This is a specimen of green emerald beryl from Bullabulling in Western Australia.
