Aquamarine General Information
Aquamarine is beryl. Beryl also contains other gem varieties, including emerald
and some lesser known varieties (such as morganite and heliodor). Light
green beryl can be transformed into aquamarine if heated to 750º F (400º
C). The green hues in regular aquamarine can also be removed through
heating. In fact. almost all aquamarine gems on the market today are heat-treated.
Generally, the deeper the blue in aquamarine, the greater its value. A
very dark form of beryl resembling deep blue sapphire is artificially
formed by irradiating
certain beryls. These dark blue stones are not called aquamarine but
"blue beryl".
Aquamarine is
a fairly common gem, and is thus affordable. Some enormous transparent
crystal masses have been exploited, and exquisite gems weighing
thousands of carats have been cut from them. The beautiful light blue to
blue-green colour of aquamarine may fade upon prolonged exposure to
light, so it is especially important to purchase this gem from a
reliable dealer.
Light blue
topaz is easily mistaken for aquamarine. The colours of these two gems
are identical, and their physical properties are very similar. Topaz is
the less expensive gem, and some crooked dealers may sell their topaz as
aquamarine.
Unlike
emerald, aquamarine gems are often completely flawless.
In fact, an aquamarine gem with a visible flaw is rarely seen. The costs
of producing synthetic aquamarine are very high when compared to the
relative abundance of this gem, so synthetic aquamarine is not available
on the market. However, production of synthetic blue spinel is easy and
inexpensive, so it is used as a cheap aquamarine simulant. It is often
mistakenly sold as "Synthetic Aquamarine".
Aquamarine
is a hard and durable gem, but occasionally develops internal cracks if
banged hard. Its colour may fade upon prolonged exposure to light.
