摘要： A gemstone is provided that has an improved brilliance, especially at the crown portion of the gemstone. The gemstone has a crown angle that is less than an ideal cut round diamond and, preferably the crown angle is less than 27 degrees. By reducing the crown angle of the gemstone, light entering one end of the crown portion may exit the opposite end of the gemstone. In addition, reducing the crown angle reduces the mass necessary for the gemstone. As a result, the gemstone has a width or diameter that corresponds to a larger mass gemstone that is cut according to conventional ideal proportions.

摘要： A system for grading the cut of a diamond utilizes a number of appearance metrics to generate scores for a number of cut components that affect cut quality. These cut components include brightness, fire, scintillation, overweight, durability, polish, and symmetry. The cut grading system employs a cut grading algorithm that processes the individual scores obtained for the cut components to generate an overall cut grade for the diamond. The scoring methodology and the cut grading algorithm are designed to emulate actual observation grading such that the overall cut grade represents a fair indication of the cut quality of the diamond. In one practical embodiment, the cut grading system is fully automated and computer-implemented.

摘要： An oval-cut diamond comprises a girdle having a contour line in an oval or oval-like shape, a crown above the girdle having an octagonal table facet on a top of it and a pavilion below the girdle. The girdle is of a ratio (b/a) of a short radius to a long radius of 0.6 or more, in which a radius in long axis direction is “a”, and a radius in short axis direction is “b”. A pair of pavilion main facets positioned opposite to each other with respect to a central axis has a pair of crown main facets or star facets facing the pair of pavilion main facets through the girdle. The two pavilion main facets, the two crown main facets or star facets and the table facet have a common vertical plane within the facets so that brilliancy of reflection lights coming out of the table facet and crown facets is enhanced.

摘要： A new method of cutting a gemstone such as a diamond, known as the “Galush” cut, is provided. According to an embodiment of the invention, the “Galush” cut gemstone has a crown portion, a pavilion portion and a girdle portion provided between the crown portion and pavilion portion. The crown portion includes an upper surface having a shape configured by first, second and third boundaries, which form a perimeter around the crown of the gemstone. Each of the first and second boundaries has first and second ends, and the third boundary is arc-shaped having first and second edges. The first and second edges of the arc-shaped boundary adjoin the first end of each of the first and second boundaries and the second end of each of the first and second boundaries meet at a common tip.

摘要： Disclosed is a diamond cutting method comprising the steps of: forming a square or rectangular table in a piece of gemstone; and forming a pavilion continuous to the table by cutting vertically from each side of the square or rectangular table to define the four lower-girdle facets and by cutting obliquely from each corner of the square or rectangular table to the culet of the pavilion to form four lower-main facets, whereby the upper opposite sides of each lower-main facet adjoining the adjacent lower-girdle facets whereas the lower opposite sides of each lower-main facet adjoining the confronting lower opposite sides of the adjacent lower-main facets. An enneahedral-cut diamond thus produced is a table-and-pavilion structure, permitting plural diamonds to be arranged side by side as a whole with their square or rectangular tables directed inward or outward.

摘要： A brilliant gemstone cut, having a crown, a girdle and a pavilion. The crown has a flat table shaped as an equilateral n-sided polygon. The girdle is also multi sided polygon. The corner, lower girdle, bezel and star facets are at significantly angles of inclination, with respect to the table to provide significantly improved brilliance. The upper corner facets are spaced from the girdle. The space between the corner facet vertices and the girdle is left open to be covered by a prong of a jewelry setting.

摘要： A stone cut and method for cutting a stone that increase the number of facets on the stone as well as the scintillation, brilliance, and light reflectivity of the stone. The cut and method includes cutting angles and increased number of facets that, either separately or together, manage the external and internal light flow dynamics of a round cut diamond to a higher level of efficiency, effectiveness, and performance. In accordance with another aspect of the invention, different cutting angles and proportions generate greater brilliance, dispersion, scintillation, and light reflectivity of the stone.
