They say you're just a Stone.
But if so, Why do I feel you?
Why do I hear you?
How Comforting your Presence.
How Close when we Whisper.
Is My Need that you're There?
Or Your Need that I am Here?
Whichever Be, We have One Another.

Chrysoberyl Gemstone Information
About Chrysoberyl - History and Introduction
Chrysoberyl is a rare and exotic family of gemstones first discovered in 1789 by renowned geologist, Abraham Gottlob Werner. The name 'chrysoberyl' was originally derived from the Greek words, 'chryso' and 'beryl', meaning 'golden' and 'green', respectively. For many years, chrysoberyl was often referred to as 'chrysolite', a historical name used to refer to any golden-green to olive colored gemstone. Today, the term 'chrysolite' is no longer commonly used. Despite its name, chrysoberyl is not a beryl, although it shares a similar appearance and composition. Chrysoberyl is classified as its own independent mineral group and species - beryl is aluminum beryllium silicate, whereas chrysoberyl is beryllium aluminum oxide. Chrysoberyl is a minor ore of the element beryllium (Be) and occurs in granite and granite pegmatites.
The chrysoberyl species includes a few different gemstone varieties. The most common variety is a transparent to translucent form colored by iron, which typically occurs in shades of yellowish to light-green. This is typically the only variety traded as just 'chrysoberyl', while other varieties of chrysoberyl are traded under very specific names, which include both chrysoberyl cat's eye (cymophane), the chatoyant variety of chrysoberyl; and alexandrite, a rare color change variety named after Russian Czar Alexander II. In very rare cases, color change chrysoberyl may also exhibit a cat's eye effect, which is classified as 'cat's eye alexandrite'.

Identifying Chrysoberyl
Most gemstones have a crystalline structure that can help to identify minerals and materials. Chrysoberyl belongs to the orthorhombic crystal system, forming with tabular crystals in slender prisms. Crystal twins and triplets are quite common. Common chrysoberyl is colored by iron, while color change varieties obtain their color through chromium. Through spectroscopic analysis, chrysoberyl can easily be identified and distinguished from other similar materials. From within its own species, specimens that exhibit color change properties are traded and identified as alexandrite, while chrysoberyl that exhibits chatoyancy is traded as chrysoberyl cat's eye or 'cymophane'.
Chrysoberyl Origin and Gemstone Sources
Chrysoberyl is a very rare mineral and gemstone quality deposits are even rarer. Some of the most notable sources include Brazil's Minas Gerais, Esperito Santo and Bahia; the Mogok and Pegu regions of Burma (Myanmar), Sri Lanka (most particularly Ratnapura), India, Tanzania, Madagascar, Pakistan, Russia, Zimbabwe and the United States.
Most color change chrysoberyl is sourced from the Ural Mountains of Russia near Sverdlovsk, while most chrysoberyl cat's eye is sourced from Brazil, China, India, Sri Lanka and Zimbabwe. A rare, colorless variety of chrysoberyl is known to occur only in Burma, and Tanzania is also known to produce a very rare, bluish-green chrysoberyl which is extremely valuable.
Buying Chrysoberyl and Determining Chrysoberyl Gemstone Value
Chrysoberyl Color
Common chrysoberyl occurs in a variety of light colors, including green to yellow and golden-yellow to yellowish-green, along with various shades of brown and red. Chrysoberyl is colored by iron, while color change chrysoberyl (alexandrite) is colored by chromium. Some 'common' chrysoberyl may also contain chromium, but unless they exhibit color change, they are not traded as
alexandrite
. The rare minty bluish-green material from Tanzania is colored by vanadium.
Chrysoberyl Clarity and Luster
Chrysoberyl typically exhibits excellent transparency, although some lower grade material can occur translucent to opaque. Chrysoberyl has an extremely attractive, vitreous luster when cut and polished and it's known to occur with moderate to high levels of clarity, making eye-clean specimens quite common.
Chrysoberyl Cut and Shape
Chrysoberyl is typically faceted, with mainly brilliant or step cuts, and can be found in a variety of shapes, including oval, cushion, round and octagon (emerald) shapes. Fancy shapes, such as hearts and trillions, are quite rare, especially in calibrated sizes, but they can be found.
Chrysoberyl Treatment
'Common' chrysoberyl is not typically enhanced in any way, but some color change chrysoberyl may be dyed or oiled to enhance color, though this is not a common practice.
