Introduction

Cat's Eye Apatite Apatite gets its name from the Greek word for "cheat". That unfair title the gemstone earned from its possibilities for confusion with amblygonite, andalusite, brazilianite, precious beryl, sphene, topaz or tourmaline. Apatite, a stone seldom found in jewelry stores and virtually unknown to the general public, is beloved by collectors for its many different colors and forms. The cat's eye effect adds to the glamour of the gemstone.

Buying Cat's Eye Apatite
Color
A rare variety are rich purpled gems 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 the apatite jewelry use increased. 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 as well, 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.

Clarity
Apatite is a transparent gemstone.

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

Cat's Eye Apatite location and deposits

The Cat's Eye Apatite zodiac, myth & legend
Lesser or unknown gems share the same destiny: no access to fame, myth, legends or the zodiac scheme.

Cat's Eye Apatite Care
Care for apatite is similar to that given opals, it is heat and shock sensitive, so steamers and ultrasonic must be avoided. The stone is slightly too soft to recommend for rings.
