Aquamarine is one of several common
gemstones belonging to the beryl mineral
group. Other gemstone members of beryl
family are aquamarine, morganite,
heliodor, etc. The name “Aquamarine” is
derived from Latin phrase “water of the
sea”, an accurate description of the
gemstone's color, which ranges from a
pale green to blue. This color is caused
by trace amounts of iron that permeate
the crystalline structure. The blue
variety is the most valuable and
greenish stones are sometimes changed to
the highly prized blue shade by heating
them in an electric furnace to 842° F
(450° C). The more
intense the colour of an aquamarine, the
more value is put on it. Much more
cherished in Aquamarine is almost
entirely free of inclusions. In
addition, Aquamarine has good hardness
which makes it very tough and protects
it to a large extent from scratches.
Some traditional sources of aquamarine
are Madagascar and Brazil. This is no
more so in view of the discovery of
other sources of aquamarine in other
places such some African countries of
Tanzania, Kenya and Nigeria, Sri Lanka,
Afghanistan and Russia.
All our gemstones are completely
natural and never treated in any
form.
