Embodiment Construction

[0035] Since the shape of a cut diamond according to the invention can be explained most simply starting from the shape of an ideal brilliant cut, we will first explain the geometric layout of such an ideal brilliant cut 1 (prior art).

[0036] When there is no culet, the Ideal Brilliant Cut 1 consists of fifty-seven facets. The shape of such a diamond can range from Figures 1 to 4 derived from.

[0037] The ideal brilliant cut 1 consists of an upper part called crown 2 and a lower part called pavilion 3 . These two parts are separated by a relatively thin disc, called the waist 4 . For the purposes of the present invention, the waist 4 need not be present. When the girdle 4 is absent, the horizontal plane shared by the crown 2 and the pavilion 3 is still called the girdle. The girdle 4 itself can be faceted or unfaceted. This has nothing to do with the present invention.

[0038] Crown 2 includes thirty-three facets.

[0039] The top facets of the crown 2 lie in the h...

Abstract

A cut diamond and its cutting method. The cut diamond, characterized in that it is a convex polyhedron and has eighty-nine facets, which are thirty-two facets more than a traditional ideal-cut brilliant, in particular eight extra facets on the crown by substituting each of the eight kite facets of a traditional ideal-cut brilliant diamond by two triangular facets, namely a table break facet and a girdle break facet, which have a common edge namely the girdle break which lies in a plane parallel to the table, and whereby twenty-four of the thirty-two extra facets are added in the pavilion by substituting each of the eight lower main facets of a traditional ideal-cut brilliant with four facets, namely a bottom star pavilion, two bottom star halves, and bottom girdle pavilion, touching each other in a point, namely the meeting point, and whereby the pavilion height is approximately three percent longer than the pavilion height in the corresponding traditional ideal-cut brilliant.

Description

technical field [0001] The present invention relates to cut diamonds and methods for cutting them. Background technique [0002] The quality and value of cut and polished decorative diamonds are often described by the four C’s: [0003] -carat [0004] -Cleaness [0005] -color [0006] - cut [0007] A carat is a unit of weight for a diamond, one carat is equal to 200 milligrams. Traditionally, the value of a diamond has been determined by its size, or weight in carats. The larger the gemstone, the higher its value. [0008] Clarity refers to the blemishes and inherent impurities already present in the rough. [0009] The color is also determined by the rough stone. Colorless and transparent gemstones are rare and thus more valuable. [0010] Cut refers to the cutting and polishing of a gemstone in a specific shape with multiple facets. The way a gemstone is cut determines the path that light entering the gemstone will follow. Almost all the light that enters the...
