Mercury
Emerald
is the primary gem for the planet Mercury. As a general
rule for our needs, we are looking for eye-clean gemstones,
which means that any imperfections in the gem are
not visible to the unaided eye. Emerald is the gem
where we must be extremely lenient with this rule.
There is such a thing as an eye-clean emerald, the
last one I saw was just over 5 carats and was $35,000-
for the gemstone,
wholesale! In generally affordable
price ranges, we must be willing to accept what has
been called 'jardine' in the gem trade. That's French
for garden and is a pleasant sounding term referring
to the many white inclusions that appear like lines
or cobwebs in the gem. Emerald Beryl crystals form
with these inclusions as their hydrothermal crystal
structure occurs in the presence of water. What you
can avoid are the dark included crystals, or small
black inclusions that are common in both Brazilian
and African emerald material. The Emeralds that are
consistently free of these dark included crystals
are the Emeralds from Columbia.
Remember
that $35,000- wholesale 5 carat Emerald? That Emerald
was being sold with a gemological certificate stating
that no evidence of enhancement was detected. This
means that the Emerald was not oiled. You have to
get up into extremely clean crystals, with prices
that reflect their rarity, to avoid the oiling usually
applied to Emeralds. The oiling is to reduce the appearance
of the white inclusions much as oiling a scratch on
glass would reduce its appearance. Oiling is generally
accepted and expected in the trade. What you want
to avoid are the more harmful waxes, plastics and
resins that can be forced into the inclusions that
reach the surface of the Emerald. Also be aware that
there are Synthetic Emeralds readily available. You
want to purchase a Natural Emerald with any enhancement,
including oiling, being disclosed. Emerald Beryl has
a hardness of 7 1/2 - 8, which is quite hard yet it's
toughness, or resistance to chipping and breakage
is not good due to the inclusions. I like to point
this out as many clients choose to wear their Emeralds
in pendants at the throat chakra instead of in a ring
on the pinky or middle finger, which, especially in
the case of the pinky, can take more of a beating
than an Emerald can handle. I do make plenty of rings
with Emerald and you can see a beautiful 4 carat gem
set in a man's ring on the Custom Design page.
The
Mercury ring above is shown set with a Peridot and
was inspired by the Roman mythology of Mercury, the
'winged' messenger of the Roman pantheon. We refer
to it as the 'Wing Ring' and have set other gems into
it as well, including Jupiter gems.
Peridot
is another beautiful and usually bright green gem,
commonly used as a secondary gem for the planet Mercury.
Peridot, or Olivine, in mineralogy occurs in colors
ranging from intense yellow green to olive green to
greenish brown. One of the sources of Peridot is Arizona,
while much of the very highest quality material is
from Burma. Some of what look to be small black inclusions
in Diamond are actually included crystals of Peridot
as both Diamond and Peridot can form under similar
circumstances.
Green
Tourmaline is a gem that can be seen commonly
recommended as an alternative to Emerald. Tourmaline
is a beautiful gem mineral that occurs in every color
of the rainbow and can occur with multiple colors
in one crystal or one gem. Tourmaline grows in long,
tall thin crystals accounting for the shape you see
so commonly in cut Tourmaline, long, step-cut rectangles
(emerald cuts or baguettes.)
The
problem with Tourmaline for our Vedic uses is that
Green Tourmaline is commonly heat-treated. Unless
a certain type of inclusion is left in the gem that
indicates heat treatment there is no way gemologically
to prove that the gem is natural. Very 'clean' crystals
of Tourmaline are plentiful, therefore the majority
of cut gemstones leave no way of gemologically assuring
the client of natural Green Tourmaline. I will be
happy to supply anyone with Green Tourmaline with
the caveat that heat treatment may be present and
undetectable. We can use our other intuitive processes
to attempt to procure an unheated, natural gem yet
I cannot guarantee it gemologically. Therefore I have
chosen not to offer Green Tourmaline on this web page,
yet will be happy to get it in for special orders.
