Cut
Ideal Cut
When a round brilliant diamond has been cut to "Ideal" proportions by a master
cutter, it is a splendor to behold.
The Ideal Cut Diamond describes a round brilliant diamond that has been cut to
exact and mathematically proven proportions. Its symmetry, with 58 exactly
placed facets, produces the ultimate in lustre and beauty.
When a diamond is cut to the ideal proportions, all of the light entering from
any direction is totally reflected through the top and is dispersed into a
display of sparkling flashes and rainbow colors.
Premium Cut
A Premium Cut diamond demonstrates subtle variations from the Ideal Cut.
Although dimensional differences affect a diamond's reflection of light, a
Premium Cut still achieves a harmonious balance between it's proportions and the
display of brilliance.
Color
Most diamonds, although appearing colorless, actually have slight tones of
yellow or brown. As these tones become more easily apparent, the rarity and the
cost decrease.
Ideal cutting dramatizes the rare splendor of a diamond because it roduces such
dazzling brilliance.

Clarity
Practically all diamonds contain naturally occurring internal characteristics
called inclusions. The size, nature, location and amount of inclusions determine
a diamond's clarity grade and affect its cost.
One unique advantage of the Ideal Cut is that its sparkle can mask otherwise
noticeable inclusions.
Carat Weight
The weight of a diamond is measured in carats. One carat is divided into 100
parts called “points”, 1ct. = 1.00; 1/2 ct. = 0.50. The value of two diamonds of
the same weight can very greatly depending on the color, clarity and especially
the cut. Below are two ideal pieces of rough, uncut diamonds) each of the same
quality and value.
Example 1. From one piece of rough a diamond has been cut to Ideal proportions,
retaining a weight of one carat. The light is totally reflected through the top.
Example 2. The second piece of rough has been “spread” in its cutting, resulting
in a diamond weighing approximately 1.40 ct. Note: The gridle is thicker, the
table is much larger, the angles are exaggerated, all at the expense of that
diamond’s ability to reflect light.
Therefore, one can see that the value of a diamond can vary as much as 40% in
the cutting alone.
