The valuation of every Gemstone depends upon the “4
C's”: carat, colour, clarity, and cut.
If you are buying any expensive Gemstone you have
to know bit about all four of these (“4 C's”), Try to buy Gemstone loose so you
can check the weight of your precious Gem by yourself and can examine it
properly.
Here are the “4 C's”
colour
As Colour is one of the major factors in
establishing the value of a gemstone, same goes with emerald, the most
demanding colour of emerald is vivid green, then comes bluish green to pure
green. The most prized emeralds are the best greens (vivid green) with high
transparency with no colour zoning.
cut
The cut of the stone depends upon the shape of
rough, cut gives the stone an entirely different look. Some famous cuts of
emerald are- Step cut, Brilliant cut, Mixed cut, Cabochon cut and Achler cut.
clarity
Clarity means how gemstone looks like on the inside.
The clarity of emeralds makes them different from any other gemstone. Most
emeralds have inclusions which include minor bits of gasses, other minerals and
crystals, and liquids that emeralds take on during the crystallization process.
Carat
Carat weight plays a major role in the pricing of
every Gemstone. eg 5 carat stone is expensive than 1 or 2 carat stone. Experts
of Emerald always suggest buying smaller emerald rather than buying big one’s
reason being, smaller one with excellent colour and transparency is priceless
then the bigger one.
