Abstract
A stone cut and method for cutting a stone that increases the number of facets on the stone as well as the scintillation, brilliance, and light reflectivity of the stone. The stone cut and method includes cutting angles and increasing the 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.
Claims10
A stone, comprising:
- a pavilion portion having a culet;
- a crown portion having a table;
- a girdle separating said pavilion portion from said crown portion;
- a plurality of pavilion main facets extending between said girdle and said culet;
- at least three lower girdle facets positioned between adjacent pavilion main facets, each of said at least three lower girdle facets having a top side along said girdle, wherein only two of said at least three lower girdle facets have a common lower vertex extending towards said culet and a third lower girdle facet of said at least three lower girdle facets has a separate lower vertex extending towards said culet;
- a plurality of bezel facets extending between said girdle and said table;
- and
- at least three upper girdle facets positioned between adjacent bezel facets, each of said at least three upper girdle facets having a common upper vertex extending towards said table, wherein each of said at least three upper girdle facets has a bottom side along said girdle.
