Abstract
The invention is directed to shallow pavilion, cut diamonds having excellent optical characteristics. The pavilion surface includes a plurality of substantially planar main pavilion facets, each of which extend from the girdle to a pointed culet defining the bottom most portion of the cut diamond. The crown angle is in the range of between about 29 degrees to about 36 degrees, and the pavilion angle is in the range of between about 15 degrees and about 34.5 degrees. The shallow pavilion, cut diamonds of the invention may be either round shaped cut diamonds or fancy shaped cut diamonds.
Claims24
A round cut diamond comprising:
- a crown including a table and several crown facets, some of said crown facets extending downwardly from said table at a crown angle in a range of 33-35°;
- a girdle, the girdle being below the crown;
- and
- a pavilion including several pavilion facets, the pavilion extending downwardly from the girdle at a pavilion angle in a range of 30-33° to a single-pointed culet,
- wherein the round cut diamond is configured so ambient light enters the table and follows a path including reflection from at least four interior diamond surfaces before the reflected light exits through the table.
