Aquamarine is one of the most popular and well-known gems. The name
comes from the Latin aqua marina, meaning “water of the sea,” referring to the
stone's delightful blue to turquoise color for which it is so popular. Aquamarine is a type of Beryl, a mineral composed of beryllium aluminum silicate. The
English word for brilliance can be traced back to beryl's etymology, which
goes back to Dravidian origin in southern Asia. Pure beryl is colorless. Often,
the stone is found tinted with impurities. The blue color of aquamarine is
created by traces of iron. Green beryl is called emerald, yellow is heliador, red
is red emerald, and pink is morganite.
Most aquamarine has a very light tone, but the more saturated the color, the higher the value. Blue aquamarine
fetches a higher price than turquoise ones. Very deep blue aquamarine is called Maxixe, and commonly comes from
Madagascar. Because aquamarine is generally very clean, high quality stones should be expected to be clean at
least to the naked eye. Small inclusions are considered acceptable if the color is quite good. But most aquamarines
are almost completely clean, even under a jeweler's loupe (10x magnification).
Some aquamarine features aligned traces of foreign minerals,
causing a cat's eye or star (asterism) effect. These pieces command premium prices. Large aquamarines are not uncommon,
but top grade stones of good color are rare and pretty expensive
in sizes over 10 carats. Still, the price is quite attractive, at
$150-$200 per carat. Favored cuts are emerald and brilliant, in
long or rectangular shapes. Most aquamarines have been
heat-treated to produce the popular blue-green color from
less-desirable yellow or pale stones. The heating treatment is
usually undetectable, since the temperatures used are low
enough not to affect internal structures. Brazil is the leading
