Abstract
A multi-stone setting for four gemstones, including a rectangular-shaped setting having a four-sided frame member with a first crossbar extending in a first direction and a second crossbar extending in a second direction perpendicular to the first direction. The first and second crossbars form four seats each for receiving one of the four gemstones, wherein the four gemstones each include a side wall having a groove. The first crossbar is seated within the four grooves for keeping the four gemstones seated in the four seats. The setting also has four corners with four prongs mounted on the four corners, respectively; wherein each of the four prongs has a V-shaped configuration for engaging two side walls of one of the four gemstones. Each of the four V-shaped corner prongs cooperate to engage and to keep one of the four gemstones seated within the four seats of the setting.
