Diamond Jewelry
 |
Katzo is just one of the several premier designers of
diamond jewelry you'll find at Milner's Jewelers. From classic to
contemporary and from simple to elegant, we offer diamond jewelry of
distinction - diamonds that get noticed. |
The Four Cs
The value of a diamond is not determined by a single factor. Rather, it is
the combination of several elements - cut, color, clarity and carat weight that
allows us to assess the quality of these special jewels.
1. Cut
The 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 luster 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. |
 |
The 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 its proportions and
the display of brilliance. |

Diamond Cut and Light
Ideal and Premium Cut Diamonds
 |
THE IDEAL CUT
Light* entering the diamond reflects internally from facet to facet and
is reflected back through the top ONLY, creating maximum brilliance.
|
 |
Inferior Cut Diamonds
Most diamonds are "spread" in their cutting to retain maximum weight from
the original rough. A heavier diamond will result, but at a dramatic
sacrifice of potential fire and brilliance.
 |
TOO DEEP
When a diamond is cut too deep, light* leaks out of the bottom,
brilliance is lost and the center of the diamond will appear to be dark.
|
 |
 |
TOO SHALLOW
When a diamond is cut too shallow, light* leaks out of the bottom,
brilliance is lost and the diamond appears watery, glassy and dark.
|

2. 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 produces
such dazzling brilliance. |
|
|

4. Carat Weight |
|
The weight of a
diamond is measured in carats. One carat is divided into 100 parts called
"points", 1 ct. = 1.00; 1/2 ct. = 0.50. The value of two diamonds of the
same weight can vary greatly depending on the color, clarity and especially
the cut. To the right are two identical 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 girdle 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. |
