NEBULA BERYL

Beryl is a mineral composed of beryllium aluminum cyclosilicate, and it is relatively common in the Earth's crust.
However, the occurrence of gem-quality beryl, which includes well-known varieties such as emerald, aquamarine, and morganite is less common.

The rarity of gem-quality beryl depends on various factors, including the specific variety, color, clarity, and size of the crystals. For example, Pezzottaites and Bixbites are far rarer and more valuable than other beryl varieties due to their vibrant colors and extremely limited production.

Beryl deposits can be found in various locations around the world, including Brazil, Colombia, Zambia, Afghanistan, and Russia. The overall rarity of gem-quality beryl contributes to its value in the jewelry market, but it's important to note that while certain varieties and qualities of beryl are considered rare, the mineral itself is not exceedingly scarce in geological terms.
