Ketu

Chrysoberyl Cat's Eye is the primary gem for Ketu, the South Node of the Moon. Chrysoberyl is a gem species that occurs as Cat's Eyes, Alexandrite and as transparent greenish yellow crystals. The 'cat's eye' is called chatoyancy and occurs due to numerous needle-like inclusions all oriented in one direction. When the gem is cut 'en cabochon' or in a dome, the needle-like inclusions are cut at slightly different lengths. When light bounces off of these inclusions lined up across the gem, the cat's eye appears. Many gem materials have Cat's Eye varieties such as Tourmaline, Quartz, Zircon and Beryl and the mineral species name would precede Cat's Eye, i.e. Tourmaline Cat's Eye. When we say only Cat's Eye we are referring to Chysoberyl Cat's Eye. Look for as sharp, straight and clear an 'eye' and as translucent a gem as possible. Chrysoberyl is associated with the infrared ray, the invisible wavelengths at the hot end of the spectrum.
