Beryl is a beryllium aluminum silicate that occurs in every
color of the rainbow. When green, it's an emerald.
When blue, it's aquamarine.
When pink, it's morganite.
There is a raspberry red variety found in Utah called Bixbite.
Yellow is heliodor and colorless
is goshenite. There is a very rare and costly variety termed
riesling beryl, that can be
described as pale green colour, with a warm golden yellow
flash. Beryl had been used as a physician's tool and gazing
stone since ancient times. Those beliefs persist today.
Beryl is metaphysically attributed with the ability to cure
a number of intestinal and stomach ills, such as nausea,
ulcers, and seasickness.
