Cat's Eye describes a gemstone polished into a cabochon that displays a narrow band of concentrated light going accross the width of the stone. This effect, known as chatoyancy, or cat's eye effect, is caused by inclusions of fine, slender parallel mineral fibers in the gemstone that reflect light in a single band. Of all the gemstones that exhibit cat's eye, Chrysoberyl Cat's Eye is the best known. Chrysoberyl has the strongest and most distinct cat's eye effect of all gemstones. Though several different gemstones types exhibit a cat's eye effect, only Chrysoberyl's cat's eye enjoys the privilege of having the name "Cat's Eye" without any prefix. Whenever the term "Cat's Eye" is used, it refers to Chrysoberyl cat's eye by default, unless otherwise specified.

Chrysoberyl Cat's Eye

About Chrysoberyl

Chrysoberyl term originates from the greek words chrysos and beryllos, meaning "a gold-white spar". Generally chrysoberyl is confused with beryl which is a completely different mineral. Chrysoberyl is the third-hardest natural gemstone and lies between Corundum and Topaz on Moh’s Hardness scale having hardness of 8.5. Cat’s Eye or Cymophane is a gem variety of chrysoberyl which shows the optical effect known as Cat’s Eye effect or Chatoyancy.

Cause of Cat’s Eye Effect or Chatoyancy

Cat’s Eye effect is seen in chrysoberyl containing microscopic tubelike cavities or needlelike inclusions of rutile which occur parallel to the c-axis of the crystal. When these are cut en cabochon perpendicular to the c-axis, a single ray of light can be seen to move on the surface. This effect is termed as Chatoyancy. Chatoyancy comes from the French 'chat' (for cat) and 'oeil' (for eye). Chrysoberyls lacking the cat's eye effect are mostly faceted, Cat's eyes are always cut into cabochons, since only tall, rounded shapes render the line of the eye properly visible.

History of Cat’s Eye

Cat’s eye became popular since the end of the 19th century when it was given as engagement token by Duke of Connaught. This greatly increased its value as a gemstone. The increased demand in turn created an intensified search for it in Ceylon.

Cat's Eye color

The range of colors includes colorless, pink, yellow, green, blue and violet.

Ordinary chrysoberyl is yellowish-green and transparent to translucent. When the mineral exhibits good pale green to yellow color and is transparent, then it is used as a gemstone. The three main varieties of chrysoberyl are: ordinary yellow-to-green chrysoberyl, cat's eye or cymophane, and alexandrite. Yellow-green chrysoberyl was referred to as "chrysolite" during the Victorian and Edwardian eras, which caused confusion since that name has also been used for the mineral olivine ("peridot" as a gemstone); that name is no longer used in the gemological nomenclature.

Cymophane is popularly known as "cat's eye". This variety exhibits pleasing chatoyancy or opalescence that reminds one of an eye of a cat. When cut to produce a cabochon, the mineral forms a light-green specimen with a silky band of light extending across the surface of the stone.

Buying Cat's Eye

Color

A rare variety is a rich purple from Maine. Blue Brazilian stones are second in demand. A

light green variety of apatite carries the trade name "asparagus stone". The recent availability of the neon blue-green variety from Madagascar has increased the use of apatite in jewelry. The color of the best specimens of this type rivals the famed Paraiba tourmalines, but unfortunately, this gem lacks their toughness and hardness. As for any other gem, color saturation defines the value.

Lighting

Chatoyancy, the cat's eye effect, is a reflection of light by parallel fibers, needles, or channels, which resembles the slit eye of a cat. When the stone is rotated, the cat's eye glides over the surface.

Cut

The cabochon cut is excellent for a unique brooch or pendant, if its base is parallel to the fibers.
