Diamonds with few flaws, or inclusions, are very rare
and highly valued. Clarity is graded based on the number, location, size, and type of the
inclusions found in a diamond. JMC offers some of the clearest diamonds available. Review
your Clarity diagram and learn how to choose the right grade of clarity for your diamond.

Diamonds with very little color are the most highly
valued and are priced accordingly. A little color can diminish a diamond's brilliance.
To help you choose the most brilliant diamond, JMC offers diamonds with the highest
grades of color. Review our Color chart and learn how to choose your diamond with no
color noticeable to the unaided eye.

The weight of a diamond is measured in carats.
Since larger diamonds are more rare than smaller diamonds, diamond value tends to rise
exponentially with carat weight. So, a 2-carat diamond of a given quality is always worth
more than two 1-carat diamonds of the same quality.

The cut of a diamond, or its roundness, its
depth, width and uniformity of the facets determine a diamond’s brilliance. Many
gemologists consider cut the most important diamond characteristic. Even if a diamond
has perfect color and clarity the cut may be poor, therefore, the diamond will have a
dulled brilliance. The width and depth have the greatest effect on how light travels
within the diamond and how the diamond exudes brilliance.
|
|
If the diamond is cut too shallow the light is
lost from the bottom causing the diamond to loose brilliance. Conversely, if the diamond
is cut too deep light will escape out of the sides causing the diamond to appear dark and
dull.
