The Greeks proclaimed
this highly prized, light blue gem aquamarine, because
it sparkles like the sea touched by the sun. Found in
an array of pastel tones from very light to medium blue,
aquamarine is often tinted by a splash of green.
The
delicate greenish blue of a fine aquamarine conjures
up images of dancing light on the purest of tropical
waters.
Aquamarine holds its place securely among the world’s
most desirable gems. Ranging in tone from a very light
to medium blue, many aquamarines will exhibit a slight
tint of green in their body color.
Generally the darker
shades are more valued, but many people prefer the lively
brightness of lighter hues. Aquamarine is readily available
in larger sizes over 5 carats. In fact, gem quality aquamarine
crystals weighing several hundred pounds have
been discovered.
Birthstone
Aquamarine is the birthstone for March.
Origins
Today’s most important source for aquamarine is Brazil. Other sources include
Zambia, Nigeria, Madagascar and the United States.
Treatments
Virtually all aquamarine is heated to minimize the greenish component of its
color, making it appear a purer blue. Heat treated aquamarines are generally
stable, but their color may fade if exposed to prolonged periods of high heat
or direct sunlight.
Care
Aquamarines should never be cleaned with a steam cleaner or an ultrasonic cleaning
machine. Aquamarines can be cleaned with most any commercial jewelry cleaner
or plain soap and water using a soft brush. Be sure to rinse and dry your jewelry
thoroughly after cleaning.
