Aquamarine and emeralds.

Be3N2 That is 3 beryllium atoms + 2 Nitrogen atoms
The Atomic Mass Of Beryllium Is 9.01218
Beryllium's crystal structure is hexagonal.
Beryllium is an alkaline earth metal. It has an atomic number of 4. By looking at this spot on the periodic table, one finds that beryllium has the atomic symbol Be.
=Beryllium is found in gems such as emerald and aquamarineMagnseium is found in the chlorophyll of green plants=
It was found in emeralds from the mountains of France and California. ------ The first mineral with beryllium was an emerald from Peru, studied by the German chemist Klaproth; similar gems were analyzed by Bindheim and Hauy. In 1798 the French chemist Vauquelin identified in the gems a new metal oxide, initially called glucina. After 30 years Bussy and Wohler, separately, isolated the pure metal by reacting potassium and beryllium chloride.
Formula of beryllium oxide: Be(OH)2
Pure beryllium is not found in nature. Beryllium compounds can be found in 30 different mineral rocks, soil, coal, oil, and volcanic dust.
Don't know where it's found, but am sure that beryllium and beryllium compounds are very toxic Category 1 carcinogens; they are carcinogenic to both animals and humans.

Beryllium is a solid metal at room temperature.
The most importants mines of beryllium are in USA, China and Kazakhstan.
Important minerals of beryllium: beryl, chrisoberyl, phenakite, bertrandite.

Emeralds are green gemstones that contain the element chromium, which is responsible for their color. This element gives emeralds their characteristic rich green hue.
