Much like any high-school student, a diamond is marked with a grade when
it comes out the other end of the cutting process. There are two
separate organizations running the examination show, GIA and AG:s. And
just like in high-school, where you get graded on everything from math
sac longchamp pas cher to gym, a gemstone also has its different subjects.
Diamonds - From Rough Cut To Precious Gem
Diamonds pass through many steps of the ladder commonly called the chain
of supply. Every hand involved in this process, also means a step up in
market price for the finished retail item we achingly lust for when we
are out window-shopping.
The four C's of the trade is the holy grail of this business and a
template to judge the quality of a gemstone that everybody has to
subject themselves to. The four C's meaning: cut, color, clarity and
carat.
The number one priority for a jewelry appraiser is looking at the so
called table of the stone, which is the top part of it where the facets
are easiest to judge. Depending on what type of cutting process the gem
has been put through, that area varies in size accordingly. The biggest
flat top area on a gemstone is called the emerald cut. To perform this
type of cut, you really need a stone that can stand the test of time and
that can pass under the most scrutinizing magnifying glass belonging to
the most thorough Antwerpen appraiser. Because it is from this area,
the table, that an appraiser targets his critical eye when he is looking
for facets. So therefore, a stone where the color or clarity is not
holding up to industry standard, will immediately be discovered in an
emerald cut.
Polish and symmetry are judged by the GIA in a falling scale from
"excellent", "very good", and just plain old "good". If a stone does not
measure up to good it does not get their diploma, instead they are sent
straight away to be used in industry equipment. AGS also grade in a
falling scale from ideal (D) down to good.
GIA then continues to grade the

color, where the top student gets awarded with a big D and then the
color grading of a gemstone trails down the full list of the alphabet. A
stone marked with a grade from D to K is practically colorless, which
of course is what every appraiser is looking for sitting there with
their eye pressed against the loupe, but to find one is about as common
as winning the high price on the national lottery.
After that they move on, judging a gemstone on its clarity and the carat
so when it is installed in the most beautiful engagement ring you have
ever seen, you can ask your designated jeweler to see the standard
paperwork for any given stone. If your jewel is graded with a 0 from AGS
it means the clarity is completely flawless, inside and out and every
which way you look at it.
Now go out searching for those grade A diamonds.
