Aquamarine ranges in color from light to deep greenish-Blue through blue-Green. The richer the color,
the more costly the gem is per carat. Aquamarine achieves its Blue
to greenish Blue color from Iron in the ferrous state. Its name is
from two Latin words meaning "water" and "sea". Aquamarine amulets were thought
to render sailors fearless and protect them from adversities at sea, especially
if the stone was engraved with a Poseidon on a chariot. The stone was symbol of
happiness and eternal youth, and according to Christian symbolism, it signified
moderation and control of the passions to it's owners.
Aquamarine is a member of the Beryl (BARE-ul) mineral family, along with Emerald,
Golden Beryl, Goshenite, Bixbite and Morganite. Brazil is the principal
source for Aquamarine. More than 80% of the the Brazilian Aquamarine comes from
an area around Teofilo Otoni in the western part of Minas Gerais.
The light blue of this fine Beryl finds more and more
friends. The different shades of Aquamarine are distinguished by their own
names: Santa Maria is the name for the rare, intensely deep blue Aquamarine
found in the Santa Maria de Itabira mine in Brazil, and they are very
collectible among gemstone lovers in general. Similar colors are found in some
of the smaller Aquamarine gemstone mines in Africa, especially in Mozambique. In
order to better distinguish them, these Aquamarine gemstones are denoted as
Santa Maria Africana. The Espirito Santo Aquamarine gems from the Brazilian
state of Espirito Santo are not quite as deeply blue. Another beautiful color,
Martha Rocha, was named in honor of a Brazilian beauty queen from 1954.
Aquamarine is
also found in China, Pakistan, Afghanistan, Madagascar, Malagasy Republic, Nigeria, Zambia, U.S.
in Maine as well as Idaho and California, and the
former Soviet Union in the Ural Mountains, as well as Transbaikalia and Siberia.
Aquamarine gemstones with intense colors are becoming very scarce, and their
price has increased substantially. Top colors according to the GIA color
grading system have 2-4 tones, with 1-4 saturation.
TREATMENTS - The bright sky blue shade is now produced by heat treating the
greenish-yellow, greenish, and even brownish beryl gems, so you should assume that
all Aquamarine "may have been" treated. The heat treatment process is a permanent process that does not adversely
affect the performance and durability of the gemstone, so there's no need
to worry when you see this enhancement disclosed.
CARE - Aquamarine should not be
cleaned in an ultrasonic or steam cleaner. We recommend Ionic
Cleaners and/or warm, soapy water and a soft brush as the best way to clean
your gemstone jewelry.
