Kerman Province, Iran Demantoid garnet is one of the most valuable members of the garnet family--chatoyant demantoids are almost never seen. The few examples which have reached the market originated from the central Ural Mountains in Russia. However in 2001 a new source of demantoid garnet was found in Kerman Province, between the villages of Bagha Borch and Soghan) in the south-east of Iran. Less than 0.1% of the material found there was seen to have any cat's eye effect. The cat's eye effect in Iranian demantoid may apparently be caused by long parallel fibrous inclusions (possibly chrysotile or byssolite). When this material was compared to cat's eye demantoid materials from the Klodovka Mine, in the Ural Mountains in Russia, their crystal forms, color distribution and the types and orientation of inclusions were seen to be different. The present oval cabochon cat's eye of rich green color demonstrates a strong cat's eye effect. Weighing approximately 5.18 carats and measuring 10.11 x 7.85 x 6.40mm
