A Message From A Master Cutter

This information is designed to afford the discerning buyer the opportunity to study the aspects of a diamond's qualities and how these qualities relate to its beauty and value.

A clear understanding will add to one's enjoyment and confidence in the purchase of a finely cut diamond.

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 diretion is totally reflected through the top and is dispersed into a display of sparkling flashes and rainbow colors.

 

Cut

  • 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

  • Inferior Cut
    Most Diamonds are "spread" in their cutting to rretain maximum weight from the original rough.A heavier diamond will result, but at a dramatic sacrifice for potential fire and 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 cose decrease.

Ideal cutting dramatizes the rare splendor of a diamond because it produces 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." 1 ct. = 1.00; 1/2 ct. = .50. The value of two diamonds of the same weight can vary greatly depending on the color, clarity and especially the cut. Below 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 1 -

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 thicher, the table is much larger, the angles are exaggerated, all at the expense of that diamond's ability to reflect light.


- Example 2 -

Therefore, one can see that the valure of a diamond can vary as much as 40% in the cutting alone.
