Description

FIELD OF INVENTION

The present invention relates to the field of diamonds, particularly diamond cuts having a brilliant cut pavilion and crown.

BACKGROUND OF THE INVENTION

There are many brilliant gemstone cuts available that achieve good brilliance, dispersion and scintillation. However, there is a long felt need for a better gemstone cut. The present invention fulfills that need by providing a brilliant cut that achieves excellent brilliance, dispersion and scintillation.

The prior art patents present certain problems and do not fulfill the need for a better diamond cut.

U.S. Pat. No. 2,364,031 to Suderov shows a brilliant cut diamond with a table that is in the form of a twelve-sided polygon.

U.S. Pat. No. 3,286,486 to Huiman discloses a brilliant cut diamond having a pavilion with seventy-two facets, but not having the same number of bezel facets or pavilion or lower girdle facets as in the present invention, and therefore lack the brilliance of the present invention.

U.S. Pat. No. 3,585,764 discloses a brilliant cut gemstone which lacks the number of bezel facets or pavilion or lower girdle facets as the diamond cut of the present invention and, therefore, lacks the brilliance of the present invention.

U.S. Pat. No. Des. 217,634 to Bochner discloses a brilliant cut gemstone with a limited number of bezel facets and pavilion facets, thus impeding its brilliance.

U.S. Pat. No. Des. 287,232 to Ishida discloses a brilliant cut gemstone with a multiplicity of bezel facets. However it does not have both upper and lower bezel facets or multiple part lower girdle facets of the present invention.

U.S. Pat. No. D 451,427 discloses split bezel facets, but lacks multiple part pavilion facets.

SUMMARY OF THE INVENTION

The present invention is directed towards a gemstone cut.

The main object of the present invention is to provide a brilliant cut gemstone, with a brilliant cut crown, girdle and brilliant cut pavilion.

It is another object of the present invention to provide a brilliant cut gemstone that provides good dispersion, brilliance and scintillation by having multiple part bezel facets and multiple part lower girdle facets.

Other objects of the present invention will become apparent from the foregoing description.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The invention discloses a brilliant cut round gemstone that has multiple bezel, and pavilion facets to substantially enhance its brilliance.

Referring to FIG. 1, a round gemstone 10 is shown from the top. The gemstone 10 has a brilliant cut crown 12, a flat table 16, upper bezel facets 18, lower bezel facets 20 and upper girdle facets 28 and 30.

Referring again to FIG. 1, the table 16 is elevated 32° to 40° off the surface of the girdle 50 plane. The table 16 is in the form of a right octagon having vertices 21. The vertices 21 serve as vertices for upper bezel facets 18, which can be either equilateral or isosceles triangles having their bases 67 coincident with the bases of girdle facets 20. The crown 12 also has star facets 23 which can also be either equilateral or isosceles triangles. The star facets 23 have vertices 25, which are coincident with the intersection of two upper girdle facets 28 and 30. The bases 32 of the star facets 23 are the sides of the octagon that forms the table 16. The girdle 50 is circular.

The degree on inclination with respect to the girdle's plane of star facets 23 may range from 30° to 40°. The inclination, with respect to the girdle's plane of the upper girdle facets 28 and 30 may range from 30° to 36° and 34° to 40°. Those angles are the preferred embodiment. However, the present invention is not limited to these particular angular inclinations.

Referring to FIG. 2, the gemstone cut 10 is pictured showing its pavilion 32. The pavilion 32 has a culet 34, which in this particular embodiment is a point culet, but can be a flat culet having a facet The pavilion comprises rib lines 36, which subdivide the pavilion into equal pavilion facets. The rib lines 36 run from the girdle plane and converge at the culet 34. There are eight rib lines. The pavilion 32 has pavilion facets 40, which subdivide the pavilion into sixteen equivalent lower girdle facets 46 and 48. Each pavilion facet 40 is shaped as an elongated diamond with one of its vertices being the culet 34 of the pavilion 32 and the opposite vertex being the girdle 50. The sides of the pavilion facets are edges 42 and 44, and rib lines 36. The two side edges 42 and 44 form the vertex 41 located at the girdle 50, and are the sides of the lower girdle facets 46 and 48. The sides of the pavilion facets 42 and 44 are equal in size.

The rib lines 36 form an equal number of equivalent lower girdle facets 46 and 48. The lower girdle facets 46 and 48 are triangles with a rounded side 52 located on the girdle's plane and with two sides 42 and 44 along the sides of the pavilion facets. The inclination of the pavilion facets 40 with respect to the girdle's plane in this particular embodiment may range from 53.8° to 59.8°, however, other inclinations may be used. The pavilion also contains an even number of pavilion facets 40 and an equal number of lower girdle facets 46 and 48. Facets 46 and 48 are divided by the rib lines 36 and the pavilion facets.
