Clarity
is defined as the degree to which the stone is free of
inclusions. Unlike a shape, size or weight, the factor of
clarity is not as easy to determine. Clarity ranges from
gemstones which appear perfect under a 10X magnifier (called
flawless) to those which show a major number of flaws to the
unaided eye. In between are gemstones that are called "eye
clean" which we usually call "EC". The more
expensive the gemstone type, the more clarity faults or flaws
are acceptable. An emerald with flaws visible to the unaided eye
is acceptable; a garnet with such flaws might not be.

Color
As
like same clarity, color factor is also slightly difficult to
determine because it applies according to stone like all
colorless gemstones such as silver topaz or diamonds, should be
as colorless as possible and colored gemstone should have that
color as rich as possible. In almost all cases of faceted,
colored gemstones, the color should be as deep as possible
without being opaque.

Cutting
and Finishing
In
faceted gemstones there are a number of different cuts like
Diamond cut (round), Emerald cut (rectangle with cut off edges),
Rose cut, Checker Broad, Princess cut, the most common cut and
there are hundreds of other cuts which have been used. For
faceted cuts the important factor is uniform, well polished
facets that are made at the proper angles. For very valuable
gemstones like diamonds, a perfect facet series is often passed
over to maintain as high a weight as possible.
In Cabochon,
the cut should be a uniform dome that is highest in the exact
center. No cracks should show. All cabs should show a proper
sheen or luster and have a high polish.
