    Jan 21, 2015  Beryllium is an element that occurs naturally. It is present in a variety of materials, such as rocks, coal and oil, soil, and volcanic dust. Two kinds of mineral rocks, bertrandite and beryl, are mined commercially for the recovery of beryllium. Very pure gem™quality beryl is better known as either aquamarine (blue or blue-green) or emerald (green).
