DESCRIPTION

TECHNICAL FIELD

[0001] The present invention relates to the field of jewelry, and more particularly, to a diamond with eighty-one facets having a ten hearts and ten arrows inner structure.

BACKGROUND OF THE INVENTION

[0002] With the improvement of people's standard of living, the jewelries as people's ornaments are more and more widely used, in which the diamond jewelries are especially prominent. In a quality evaluation of the diamond, four aspects of color, clarity, carat, and cut are considered primarily. Because their English names all begin with the letter of "C", these four standards are called 4C for diamond. Because the color, clarity and carat are its own properties during diamond formation and can not be altered, only cutting can endow the diamond with better quality and value and endow the diamond with more brilliant radiance. With the continuous development of the cutting technology, the diamonds that present inner eight hearts and eight arrows radiance after light refraction and reflection are loved by the users, and it is now also an advanced cutting method for the diamond.

[0003] US 2009/0056374 A1 discloses a gemstone including a crown and a pavilion. The crown can include a table facet with various facets arranged in an 8 or 10 fold symmetrical pattern between the table facet and the perimeter of the crown. The pavilion can include various facets arranged in an 8 or 10 fold symmetrical pattern. US 2005/0011226 A1 discloses a gemstone including a crown and a pavilion. The crown includes a table facet with various facets arranged in a ten sided configuration or a decagon shape.

[0005] To achieve the above-described purpose, the technical solution of the present invention is a diamond with eighty-one facets having a ten hearts and ten arrows structure comprising a crown part and a pavilion part, in which girdle facets are provided between the crown part and the pavilion part, the diamond includes ten main crown facets and ten main pavilion facets; said diamond has also one table facet; and crown star facets are disposed at the junction of said main crown facets with the table facet, the number of said crown star facets are 10; and crown small facets are disposed at the junction of the main crown facet edges with the crown star facets, the number of said crown small facets is ten; and small sectors are disposed at the junctions of the main crown facets with the crown small facets, the number of said small sectors is twenty; and auxiliary surfaces of the main pavilion facets are disposed at the junctions of said main pavilion facets, the number of said auxiliary surfaces of the main pavilion facets is 20, and the angle between said main crown facets with the girdle facet is 34-35°. The length of said small sector sides is 50% of the edges, the small sectors present sector shape, and the angle between said small sectors and the girdle facets is 35.5-36.5°. The roundness of said diamond is 99-100%, the diamond height is 60.5% of the diamond diameter, the table facet diameter is 56-57% of the diamond diameter, the crown height is 14.5-15.5% of the diamond diameter, the girdle width is 2.5% of the diamond diameter, the pavilion height is 43.5- 45% of the diamond diameter and the main pavilion facet angle is 40.5-40.8°.

[0006] It is preferred that the girdle length of said crown star facets is 50% of the edge length of the main crown facets, and the angle between the crown star facets with the table facet is 15.5- 18.5°.

[0007] It is preferred that an angle between a short side of said crown small facets with the edges is 110°, and the height of the crown small facets is 75% of the height of the main crown facet edges.

[0008] It is preferred that a bottom boundary line of said main pavilion facet auxiliary surfaces is 50% of a bottom boundary line of the main pavilion facets, and the main pavilion facet auxiliary surface edge is 75% of the main pavilion facet edge.

[0009] It is preferred that the angle between said main pavilion facet auxiliary surfaces with the girdle facets is 42-42.3°.

[0010] The beneficial effect of the present invention is that: by cutting the diamond into eighty-one facets and having a ten hearts and ten arrows inner structure, not only endowing the diamond with higher quality and value by an advanced cutting technology, but also improving the brilliance of the diamond under sunlight, and its brilliance can be improved by 20-30%. When a diamond of this structure is viewed under a specialized magnifier, if viewed from the pavilion toward the crown, the "heart" effect is more obviously bright; if viewed from the crown toward the pavilion, there are numerous radial bright facets between the arrow shafts. The diamond of the present invention has more brilliance.
