OCCURRENCE
Gem
varieties of beryl have been found in several places. Emeralds of fine
quality came from Muzo and Chivor in Colombia, Bahia in Brazil, from
Ural mountains, from Australia and North Carolina. Aquamarine has been
found in Brazil, Island of Elba, from Madagascar, from the Mourne
mountains of Ireland, etc. Golden beryl is found in Bahia, Brazil.
Beryl is generally found in pegmatites. Emerald has been found in
mica-schist and in dolomite marble in Brazil.
India.—Beryl
has been found in the mica-pegmatite of Nellore and Bihar, Rajputana
and Kashmir. In Madras it has been found in Pattalai (Coimbatore
district) at a contact of gneiss and mica-schist, being a blue or
sea-green variety (aquamarine). In Mysore it has been found at
Melkote—a yellow green aquamarine in pegmatite. In Rajputana (Ajmer) a
green beryl is found in Banas at Rajmal and at Kishengarh—aquamarine.
Beryl is mined in Rajputana on a large scale and exported for use in
the preparation of metallic beryllium and its alloys.
Kashmir.—Beryl
and aquamarine are found in Kashmir at Daso, Baltistan, where a deposit
was worked in 1917. Good stones were sold at 5a. per carat at the
Wembley exhibition. It occurs in pegmatite associated with sapphires
near Soomjam, Danjal, 1| miles N.E. of Kabon, 2 miles
north-west-by-north of Hamur and 1 mile west-by-south of
Chishote.
Emeralds in Mewab.
(H. Crookshank—Indian Minerals (1947), pp. 28-30.)
During the war an extensive search was made for beryl in
Rajputana. In this attempt some green crystals were
obtained from Mewar, which were found to be as good as
the Russian emeralds which were being sent to Jaipur for
