Abstract
A gemstone assembly includes one or more gemstones and a setting having a base formed with a plurality of ribs defining one or more sockets of polygonal configuration for receiving the gemstones. Each gemstone is of a polygonal configuration corresponding to its socket, and is formed with an upper table, a lower pavilion, a girdle, and grooves extending through at least two opposed sides of the pavilion just below the girdle, the ribs of the setting being bent at their outer ends into the grooves to fix the gemstones in their sockets.

A gemstone assembly comprising:
- at least one gemstone and a setting therefor;
- said setting including a base formed with a plurality of ribs defining at least one socket of a rectangular configuration;
- said gemstone being of a rectangular configuration corresponding to said socket, and formed with an upper table, a lower pavilion, a girdle between the table and pavilion, and grooves formed through at lest two opposed sides of the pavilion just below the girdle;
- said ribs of the setting being bent at their outer ends into said grooves to fix the gemstone in said socket;
- said gemstone being formed with three groups of lower girdle facets, the first closest to the girdle forming the largest angle with respect to the table, the second group next to the first group forming a smaller angle with respect to the table, and the third group forming a still smaller angle with respect to the table;
- the lower surface of each of said grooves being substantially aligned with the juncture of said second and third groups of lower girdle facets, and the outer edge of the upper surface of each of said grooves being substantially aligned with the juncture of the first and second groups of lower girdle facets.
