Reversible Emerald _ May Birthstone

Solid Silver Back Crabtree Emerald.
Mining operations at the Crabtree Emerald Mine began in July of 1894 by J.L. Rorison and D.A. Bowman. The emeralds at the mine occur in a pegmatite vein approximately five feet wide with well defined walls. In addition to the emeralds, the vein of quartz, feldspar and mica carries several other minerals to include: garnet, schorl, yellow and green and white beryl, fluorite, etc. Mineral rights to the Crabtree were aquired by the American Gem and Pearl Company of New York in 1905. The company operated the mine several years and marketed the rock as "emerald matrix". The material was cut en cabochon. Although most of the gem material was sold as "emerald matrix", early mining operations did produce fine clear gems suitable for faceting. The deeper the shaft was sunk, the larger the emeralds that were found, many up to one inch in diameter and one inch long. The American Gem and Pearl Co. discontinued operations in 1908. The mineral rights to the property were then purchased by Edward Fortner and J.P. Grindstaff. In recent years the Crabtree was mined commercially from 1968 to 1974 during which time, fee collecting was allowed on the dumps. In the 1980's the mine was closed for some time. The mineral rights were purchased in 1984 by the partnership of Ted Ledford, Bert Roper and Dal Duppenthaler, the new owners actively mined the site. In 1985 the mine was called "Gem Haven" and public collecting was allowed on the dumps at the mine. As of 1994 the mine was closed and has set idle for many years with the occassional collector visiting the site. In 2003, Bert Roper and Dal Duppenthaler aquired sole ownership of the mine
