Beryllium is found in over 100 minerals, [33] but most are uncommon to rare. The more common beryllium containing minerals include: bertrandite (Be 4 Si 2 O 7 (OH) 2), beryl (Al 2 Be 3 Si 6 O 18), chrysoberyl (Al 2 BeO 4) and phenakite (Be 2 SiO 4). Precious forms of beryl are aquamarine, red beryl and emerald.
Beryl is sometimes found in metasomatic contacts of igneous intrusions with gneiss, schist, or carbonate rocks. [12] Common beryl, mined as beryllium ore, is found in small deposits in many countries, but the main producers are Russia, Brazil, and the United States. [11]

Beryl, a mineral that contains beryllium, has been known since the time of the Ptolemaic Kingdom in Egypt. [37] Although it was originally thought that beryl was an aluminum silicate, [41] beryl was later found to contain a then-unknown element when, in 1797, Louis-Nicolas Vauquelin dissolved aluminum hydroxide from beryl in an alkali.

Abundance (atom fraction) of the chemical elements in Earth's upper continental crust as a function of atomic number; [5] siderophiles shown in yellow Graphs of abundance against atomic number can reveal patterns relating abundance to stellar nucleosynthesis and geochemistry.
The rate of workers becoming sensitized to beryllium varies based on genetics and exposure levels. In one study researchers found the prevalence of beryllium sensitization to range from 9–19% depending on the industry. [35] Many workers who are found to be sensitive to beryllium also meet the diagnostic criteria for chronic beryllium disease ...
Most commonly found in pink, white, or Monax — a pale, iridescent hue — this pattern is increasingly rare and valuable. Jeannette Jadeite. Michigan’s Coastal Treasures / ebay.
Beryllium is unique as being the only monoisotopic element with both an even number of protons and an odd number of neutrons. There are 25 other monoisotopic elements but all have odd atomic numbers, and even numbers of neutrons. Of the 10 radioisotopes of beryllium, the most stable are 10 Be with a half-life of 1.387(12) million years [nb 1 ...
