Featured today is a natural chrysoberyl cat’s eye of 3.79 carats. The oval cut cabochon cat’s eye gemstone from Brazil has a nice greenish yellow color, sharp chatoyancy and translucence – the hallmarks of a good cat’s eye. The gemstone has been set in sterling silver as a cat’s eye Ketu Talisman.

Chrysoberyl Cat’s eye is a fairly hard stone that is 8.5 on the Moh’s Scale of hardness. Cat’s eye is found in the Metamorphic rocks, Pegmatites, which are very coarse-grained igneous rocks, usually granite, that form from water-rich magmas. They are important sources of gem material and crystal specimens. The San Diego Natural History Museum describes such gem formation in Pegmatites very simply and clearly – Picture granite as a mass of hot molten material (magma) below the surface of the earth, cooling slowly into solid rock. If part of the magma contains a lot of water, it will hold more dissolved minerals, and it will cool even more slowly than the surrounding granite. The effect of this very slow cooling of mineral-rich magma is the formation of pockets of large crystals within the granitic rock, commonly found with all the crystals pointing inward. These bodies of rock within a granite mass with large crystals are called pegmatites. Most of the spectacular crystal-producing areas in the world, including Minas Gerais (Brazil), Sri Lanka and San Diego County, are pegmatite areas.

Most of the Cat’s eye gem traded however is found in the placer deposits also – gravely river basins where it finds its way because of its heaviness. The heavier minerals after getting freed from their matrix upon weathering, get concentrated at the bottom of stream, beach, and gravels. The earliest and simpler mining and finding of gems started with scouring through such deposits.

Cat’s eye also known as Vaidurya/ lehsunia/ Bidalaksh is the gem of the South Node of the Moon or Ketu. The phenomenal gemstone is a fast acting gem and is used in a talisman to harness saatvik energies of Ketu, restore semblance, focus and direction in the life of the wearer.
