Jewel having multiple culets
First Claim
1. A multi-faceted gem cut with a table;
- a girdle;
a base; and
a main point culet, said main point culet being defined on said base by the intersection of a vertical plane passing through a longitudinal axis extending, end to end of said gem and a cross-axis at right angles to said longitudinal axis; and
at least one additional point culet located on said base between an end of said gem at said girdle and said cross axis;
wherein the number of facets extending from the girdle to the point culets exceed the number of point culets.

Abstract
A gem cut with crown facets and base facets has a table and a principal culet located along the longitudinal axis of the gem. In addition, at least one additional culet is provided between the end of the gem and the principal culet. Extending from the extra culet to the end of the diamond, at the girdle, is an end base facet. Preferably, the end base facet is at the 41° desired angle for diamonds. As so cut, the gem exhibits enhanced brilliance and the bow-tie dullness associated with side split facets is reduced resulting in overall enhanced brilliance to the stone. In the preferred embodiment of the invention, the girdle of the stone is provided with eight straight edges and the girdle is symmetrical about both the longitudinal axis and the perpendicular cross axis. In this embodiment, a pair of extra culets and end base facets are provided. According to the preferred embodiment of the invention, the end base facets are further provided with end base split facets for further enhanced brilliance.
