_Beryl Gems._--Of the beryl gems (emerald, aquamarine, and yellow
beryl) the emerald has been mined to some extent at Stony Point in
Alexander County, North Carolina, and has also been obtained at two
other places in the county. Nearly everything found has come from the
Emerald and Hiddenite mines, where during the past decade emeralds
have been mined and cut into gems to the value of $1,000, and also
sold as mineralogical specimens to the value of $3,000; lithia
emerald, or hiddenite, to be cut into gems, $8,500, and for
mineralogical specimens, $1,500; rutile, cut and sold as gems, $150,
and as specimens, $50; and beryl, cut and sold as gems, $50.
At an altitude of 14,000 feet, on Mount Antero, Colorado, during the
last three years, material has been found which has afforded $1,000
worth of cut beryls. At Stoneham, Maine, about $1,500 worth of fine
aquamarine has been found, which was cut into gems.
At New Milford, Connecticut, a property was extensively worked from
October, 1885, to May, 1886, for mica and beryl. The beryls were
yellow, green, blue, and white in color, the former being sold under
the name of "golden beryl." No work has been done at the mine since
then. In 1886 and 1887 there were about four thousand stones cut and
sold for some $15,000, the cutting of which cost about $3,000.
