Aquamarine is
a member of the beryl family and ranges in color from an almost
colorless pale blue to blue-green or teal. The most prized color is a
deep-blue aqua color. It is 7.5-8 on the Mohs scale of hardness and
gets its name from Latin words meaning water and sea.
The most
valuable aquamarines come from Brazil, but it is also mined in Kenya
and Nigeria, Madagascar, Zambia, Tanzania, Sri Lanka, Pakistan,
Afghanistan and Russia. . Aquamarines on the market today are usually
faceted, but when cut as a cabochon, they may display a cat's eye
effect known as asterism.
Some gemstones
are heated to high temperatures to enhance the color and/or clarity
of a stone. Aquamarines are often heat treated to change a blue-green
or teal colored stone to a pure blue. This results in a permanent
color change.
