Interesting facts about beryl (emerald, aquamarine)
Interesting facts about beryl
Beryl is a common mineral in the class of silicates and germanates. It crystallises in the hexagonal crystal system and is an aluminium beryllium silicate. Structurally it belongs to the ring silicates.
Beryl forms either magmatically in pegmatite and granite or hydrothermally in greisen or quartz veins. Metamorphic beryl has also been found in gneiss. It can also be secondarily enriched in the form of placer deposits in river sediments.
Some of the many places where it has been found include Minas Gerais and Pici in Brazil, Coscuez and Muzo in Colombia, Antsirabé in Madagascar, Spitzkoppe in Namibia, Iveland in Norway, Habachtal in Austria, Gilgit in Pakistan, Malyshevo and Murzinka in the Urals of the Russian Federation, Adun-Chilon in Siberia, and Keystone/South Dakota and Pala/California in the USA.
Hardness 7.5 - 8

Emerald
There are several theories as to the origin of the word "emerald". The word "emerald" was borrowed from the Greek smáragdos (green stone) via the Latin smaragdus and is related to the Sanskrit marakatam (green); however, the word is probably of Semitic origin.
Emeralds have a beautiful green colour, ranging from pale green and yellowish green to the typical emerald green and dark green.
Emeralds have been and continue to be valued by many cultures around the world as precious jewellery or gemstones. Brazilian emeralds, in particular, can fetch higher prices than diamonds of the same size because of their strong green colour.
Aquamarine
The word aquamarine comes from Latin and means 'water of the sea'.
It has a beautiful blue colour.

The varieties are bixbit, golden beryl, goshenite, heliodor, morganite.
