Embodiment Construction

[0035] Since the shape of the diamond cut according to the present invention can be explained most simply starting from the shape of the 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 be changed from Figure 1 to 4 Draw in.

[0037] The ideal brilliant cut 1 is composed of an upper part called a crown 2 and a lower part called a pavilion 3. These two parts are separated by a relatively thin disc (called waist 4). For the purpose of the present invention, the waist 4 need not be present. When there is no waist 4, the horizontal plane shared by the crown 2 and the pavilion 3 is still called the waist. The waist 4 itself may be facetted or uncut. This has nothing to do with the present invention.

[0038] The crown 2 includes thirty-three facets.

[0039] The top facet of the crown 2 is located in a ...

Abstract

A cut diamond (11), 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 (1), in particular eight extra facets on the crown (2) by substituting each of the eight kite facets (6) of a traditional ideal-cut brilliant diamond (1) by two triangular facets, namely a table break facet (12) and a girdle break facet (13), which have a common edge namely the girdle break which lies in a plane parallel to the table (5), and whereby twenty-four of the thirty-two extra facets are added in the pavilion (3) by substituting each of the eight lower main facets (10) of a traditional ideal-cut brilliant (1) with four facets, namely a bottom star pavilion (14), two bottom star halves (15), and bottom girdle pavilion (16), 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 (1).

Description

Technical field [0001] The invention relates to a cut diamond and a cutting method thereof. Background technique [0002] The quality and value of cut and polished decorative diamonds are usually described by the four Cs: [0003] -carat [0004] -Cleaness [0005] -colour [0006] -Cut [0007] Carat is the unit of weight of diamonds, one carat is equal to 200 milligrams. Traditionally, the value of a diamond has always been determined by its size or weight in carats. The larger the gem, the higher the value. [0008] Clarity refers to the existing flaws and inherent impurities in the rough stone. [0009] The color is also determined by the rough stone. Colorless and transparent gems are rare and therefore more valuable. [0010] Cutting refers to the cutting and polishing of gemstones in a specific shape with multiple facets. The way the gem is cut determines the path that the light entering the gem will follow. Almost all the light entering the gem will leave the gem again. The r...
