About Chrysoberyl - History and Introduction
Chrysoberyl is a rare and exotic group of gemstones first discovered in 1789 by renowned geologist, Abraham Gottlob Werner. 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'.
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.
Identifying ChrysoberylBack to Top
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 SourcesBack to Top
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.

Chrysoberyl Gemstone and Jewelry Care and CleaningBack to Top
Chrysoberyl is durable enough to be cleaned using ultrasonic cleaners or steamers, but care should always be taken when using these methods. Chrysoberyl is considered to be extremely hard and durable, but it can still be easily scratched by harder gems such as sapphire and diamond. For simple maintenance, you can wipe your gemstones down using a soft cloth or brush and plain soapy water. Avoid the use of bleach and other harsh household cleaners and be sure to rinse your stones well to ensure all soapy residue is removed.
Always remove jewelry before exercising, playing sports or performing any vigorous household chores. When removing jewelry, it is important to not pull from the stone, because doing so can weaken the metal or prongs, which can eventually lead to a lost stone. When storing your chrysoberyl gems and jewelry, store them separately and away from other gemstones. If possible, wrap them individually with a soft cloth and place them inside a fabric-lined jewelry box.
