If you wish to
do some research on your own, you can a good grasp
of the basics right here. Just below is information
regarding cut, clarity, color and carat. We urge you
to read this information to help you as you consider
the stone of your dreams. However because of the importance
of this decision, we recommend you consult with one
of our certified jewelers to confirm your choice and
to answer any questions you may have.
Cut
This refers to the shape or style in which a
gem stone is cut. The depth of the diamond as a whole,
and the depths of the crown and pavillion all affect
the brilliance of the gem. Through the efforts of
skilled craftsman, the proper cut reflects the maximum
amount of light back to the eyes.
Most round brilliant cut or fancy-shaped diamonds possess 58 carefully
angled flat surfaces called facets. If the diamond is cut ideally,
each ray of light that strikes the diamond is refracted back out of
the top of the stone, adding fire, brilliance and ultimate beauty to
your diamond.

Clarity
This refers to the extent to which a diamond is free of imperfections,
inclusions and blemishes. Have the jeweler show you the diamond under
a 10X magnification. Look for anything inside the diamond. A diamond
is like glass; it should be crystal clear and you should note any
small blemish inside. For example, you may notice inclusions; black
dots or black marks, white lines or feathers, or any chips around
the edge of the stone. Don't try to grade the diamond yourself, but,
have our sales associate explain the various grades so that you may
understand where this particular diamond falls within the grading
scale. If you can not see the inclusions, request that we point them
out.
As a rule of thumb, the easier it is to see the inclusion, the lower
the clarity grade should be. An inclusion in the center of the stone
receives a lower clarity grade than an inclusion of the same size,
but on the side of the diamond. A diamond that is virtually free of
inclusions is judged as flawless. In these diamonds, nothing interferes
with the passage of light nor spoils the beauty. What minute inclusions
there may be make every diamond unique. They do not mar the diamond's
beauty nor do they endanger its durability. Without high magnification,
you may never see these inclusions. However, the fewer there are, the
rarer your diamond will be.

Color
This refers to the color of a diamond when observed
from the top. Colorless or white diamonds are considered
the most valuable, normally. The color grading scale
varies from totally colorless to light color or tinted.
The difference between one grade and the next is very
subtle.
Looking at the color is easier than looking at the clarity. To
look at color, ask our sales associate to show you a certified
diamond of the same color and compare the two colors. To do this,
you need a white backdrop and a white light. Have them turn the
diamonds on their backs (top surface or table down). Look for the
slightest differences in body color. Look for yellow, brown or
grey. If the colors don't match exactly, the grading is not accurate.
While the majority of gem quality diamonds appear to be colorless,
others can contain increasing shades of yellow and brown, some
of which are referred to as "champagne diamonds."

Carat
Weight
This is the standard unit of weight, in metric terms,
used for denoting the weight of diamonds and gem stones.
The abbreviation to denote a carat is "ct."
One carat is equal to 200 milligrams (one fifth of a gram) and
divided into 100 "points" so that a diamond of 125 points
is described as a one carat and a quarter or 1.25 carats or 250
milligrams. Size is the most obvious factor in determining the
value of a diamond. However, you now know that two diamonds of
equal carat weight can have very unequal prices depending on their
color, clarity, and cuts.
Remember that diamonds of high quality can be found in all size
ranges. There are no two stones exactly alike.
