Garnet is the name of a group of silicate minerals with the general formula A 3 B 2 (SiO 4) 3, the six common garnets being almandine (Fe,Al), grossular (Ca,Al), pyrope (Mg,Al), spessartine (Mn,Al), andradite (Ca,Fe), and uvarovite (Ca,Cr).All garnets are hard (6.5–7.5 on the Mohs scale), resistant to physical abrasion and chemical attack, and have relatively high melting points.GARNET - The largest & most visited mining website in,,Another technique of mining garnet is using the vertical dig shafts into the ground, that are supported by timber beams. Pumps are used to keep the shafts from filling with water. Miners will go down into the shafts, they will actually use a hammer and chisel to cut out the garnetGarnet Mining in the Adirondacks | Lake George Guide,In 1969, the Governor of New York, Nelson Rockefeller, made garnet the New York State Gem Stone.
