A method of forming a gemstone having a crown and a pavilion, the method comprising:
- creating a crown of the gemstone, by:
- cutting a table in the gemstone, the table forming a generally horizontal upper surface of the crown;
- cutting a first set of crown facets in the gemstone;
- dividing the first set of crown facets into a second set of crown facets and a third set of crown facets in the gemstone;
- cutting a pentagonal surfaces out of portions of each of the second and third sets of crown facets to form a fourth set of crown facets from a remainder of the second set of crown facets, the pentagonal surfaces forming a fifth set of crown facets, a remainder of the third set of crown facets forming a sixth set of crown facets;
- cutting a first triangular portion from each crown facet in the fifth set of crown facets, a remainder of the fifth set of crown facets forming a seventh set of crown facets, the first triangular portions forming an eighth set of crown facets in the gemstone;
- dividing the fourth set of crown facets into a ninth set of crown facets and a tenth set of crown facets in the gemstone;
- and
- cutting a second triangular portion from each crown facet in the seventh set of crown facets and the table, the second triangular portions forming an eleventh set of crown facets in the gemstone, a remainder of the seventh set of crown facets forming a twelfth set of crown facets, and
- creating a pavilion of the gemstone, by:
- cutting a culet in the gemstone, the culet forming a generally horizontal bottom surface of the pavilion;
- cutting a first set of pavilion facets in the gemstone;
- dividing the first set of pavilion facets into a second set of pavilion facets and a third set of pavilion facets in the gemstone;
- cutting a portion from the culet and each of the third set of pavilion facets, a remainder of the third set of pavilion facets forming a fourth set of pavilion facets, the cut-out portion of the culet and the third set of pavilion facets forming a fifth set of pavilion facets;
- cutting a sixth set of pavilion facets out of portions of the fourth set of pavilion facets and the fifth set of pavilion facets, a remainder of the fourth set of pavilion facets forming a seventh set of pavilion facets, a remainder of the fifth set of pavilion facets forming an eighth set of pavilion facets;
- cutting a ninth set of pavilion facets out of portions of the second set of pavilion facets, a remainder of the second set of pavilion facets forming a tenth set of pavilion facets;
- and
- cutting an eleventh set of pavilion facets out of portions of the ninth set of pavilion facets and the tenth set of pavilion facets, a remainder of the tenth set of pavilion facets forming a twelfth set of pavilion facets, a remainder of the ninth set of pavilion facets forming a thirteenth set of pavilion facets.
