Morganite

Besides Emerald and Aquamarine , Morganite is probably the
best-known member from the fabulous multi-coloured Beryl-group .
Women all over the world love it because of its very fine pink
colour which emanates charm, esprit and tenderness.
Also Gemstones Change their Names: Pink Beryl, aka Morganite
Although it came into existence millions of years ago, Morganite
found its name less than a hundred years ago. To be precise, only in
1911, for before this the gemmologists considered "Pink Beryl”
simply a variety of Beryl in general, and not as an individual stone.
However, it is not only people but also stones who sometimes change
their names. Thus in the year 1911 New York gemstone expert G.F.
Kunz suggested to give Pink Beryl the status and standing of an
individual kind of gemstone, and it was named in honour of banker
and minerals collector John Pierport Morgan, thus receiving its
current name: Morganite.

Beryls are hard minerals consisting of beryllium aluminium silicate.
Pure Beryl is colourless. However, due to its hexagonal structure it
is able to integrate other elements such as, e.g., iron, manganese,
chromium or vanadium. If manganese is embedded in Beryl, the plain
and unexciting gemstone is turned into a pink and precious beauty:
Morganite. Today this gemstone is mainly mined in Brazil, Madagascar,
Afghanistan and California. Its excellent hardness of 7.5 to 8 on
the Mohs' scale is the reason why it is so ideally suited to being
worn.
La vie en rose....
Morganite comes in many fine shades of pink. Some are clearly pink,
others tend more towards purple. Even a slight orange hue may be
sometimes discerned – after all, Mother Nature created the ideal
gemstone colour to complement any shade of complexion. But no matter
which shade and hue, Morganite always radiates charm, esprit and a
certain tenderness. This gemstone is endowed with a wonderful gift:
even in times of high stress it will manage to let you focus on the
bright side of life. Just give it a try and see for yourself. The
sight of a Morganite cannot fail to cheer you up. A person who
decides for this stone, will be able to see "la vie en rose” even in
the grey monotony of everyday routines. Therefore, then, it is easy
to understand that for the stone healers, Morganite is considered
the typical stone to be used as the antidote to cure the problems
caused by hectic modern life: to relieve stress and provide clarity.
It will provide a pleasant feeling of relaxation, peace and joy of
life.
Colour and Cut Determine the Quality

When determining the quality, colour is the most important criterion.
Please note: This gemstone should be selected as large as possible,
for it requires a certain size to best bring out the beauty of the
stone. The rule that a higher clearness equals a higher value can
only be applied with restrictions, since a Morganite showing fine
inclusions like pure silk is also quite coveted by gemstone lovers.
The main decisive factor, then, is definitely the quality of the cut,
because it needs a expert's cut to enhance the fine beauty and bring
out the brightness of Morganite.
