Granite pegmatite, Alstead field. A beryl locality that produced a small tonnage of beryl ore (about 20 tons of beryl). Also, at times mined for feldspar and quartz. Located near the village of South Acworth.

Beryl Mountain was known in the 1820's and a famous expedition went there in 1829, led by the young Charles Upham Shepard, with Edward Hitchcock and others. By 1837, Francis Alger, noted amateur mineralogist and editor of Phillips' Elementary Treatise on Mineralogy (4th edition, 1844), had found giant beryl crystals (to 4 feet by 5 inches across one prism face = 1.22 m x 12.5 cm) and at that time were regarded as world record size. The longest reliably reported beryl from this locality is 5 feet (Cameron et al., 1954), although some reports of larger crystals (to 6 x 1 feet = 2 x 0.3 meters) appear unsubstantiated.

Early information on the locality is provided by Merrill (1869): "The most interesting locality to the mineralogist, is 'William's Ledge' or 'Beryl Hill,' celebrated for the immense size of its beryls which have been sold to cabinets, in various parts of the world....There is one of them in the Imperial cabinet - in Vienna, highly prized even in that superb collection. The Acworth beryls, when perfect, have a fine light blue green color, of that variety known as aqua marine [sic]."
