is a relatively common gemstone, and is affordable in lighter colors.
Deeper colors can command high prices. Some enormous transparent crystal
masses of Aquamarine have been found, and exquisite gems weighing
thousands of carats have been cut from them.
The light blue to
blue-green color of Aquamarine may fade upon prolonged exposure to
light, so it is especially important to purchase this gem from a
reliable dealer. Aquamarine is a hard and durable gem, but it may
develop internal cracks if banged hard.
Light blue Topaz is
easily mistaken for Aquamarine. The colors of these two gems can be
identical, and their physical properties are very similar. Topaz is
generally less expensive, and some fraudulent dealers may sell their
Topaz as Aquamarine.
Unlike Emerald, Aquamarine gems are often
completely flawless. Aquamarines with visible flaws are rarely seen. The
costs of producing synthetic Aquamarine are very high when compared to
the relative abundance of this gem, so synthetic Aquamarine is generally
not produced for the gemstone market.
