Beryl

Beryl is usually unfamiliar to the common public, even the gemstone traders. However, it is one of the many important gem minerals. Beryl is monochrome in unadulterated form; it is the numerous dissimilar impurities that bestow beryl its assorted coloration. Without these fabulous color variants, beryl would be some normal gemstone with only run of the mill fire and radiance. Emerald is the green range and Aquamarine is the blue range of beryl. Other shades of beryl are also utilized as gemstones but are not as familiar as the latter.

The greenish-yellow range is known as the Heliodor.

The pink range is known as the Morganite.

The colorless range is known as the Goshenite.

The name beryl is utilized for the red and golden variants, which are just referred as red beryl and golden beryl, respectively. Emerald is exceedingly prized and is one of the mainly valued gemstones. Its green tint is undisputed and all the other similar green gemstones are evaluated to its concentration. Emerald samplings are frequently "flawed" with mineral additions and splinters; contrasting other gems, these are measured as part of the stones' "personality." These blemishes actually help find out natural from unnaturally produced stones.

Varieties:

Colorless beryl is called goshenite, pink beryl is morganite, red beryl is bixbite or "red emerald" or "scarlet emerald," clear bright yellow beryl is "golden beryl," yellow-green beryl is heliodor, green beryl is emerald, blue beryl is aquamarine, and deep blue beryl is maxixe. Red beryl is extremely rare and is not used in jewelry as the crystals it forms are very small; it is mined primarily in Utah. Blue beryl (aquamarine) will not fade when exposed to sunlight. Maxixe is a deep blue stone that fades into white when exposed to sunlight or is subjected to heat treatment, though the color returns with irradiation. Other, unnamed shades such as honey yellow are also known.
