COLOR |
|
| Diamond color is graded on a D (colorless) to Z (light yellow) scale.
The less color present in a diamond, the more rare it is, which in turn makes
the value higher. The majority of diamonds used show very little to no color to
the untrained eye.

CLARITY |
|
| Diamond clarity is determined by the internal and external
characteristics visible under 10x magnification. Type, position, and size of
inclusions are crucial to determining clarity. The fewer inclusions and
blemishes, the better the clarity - and more valuable the diamond.

CARAT |
|
| The weight of every diamond is measured in carats. The greater the carat
weight, the rarer - and thus more expensive - the diamond. Diamond value
increases exponentially and a one-carat diamond can cost four to six times more
than a half-carat diamond.

CUT |
|
| Cut refers to the quality of a diamonds dimensions, finish,
and light performance. A well-cut diamond will reflect brilliance and fire back to
the viewer. This is why the diamond cut is often considered the most important
characteristic of a diamond.
