Abstract: A multi-stone round setting for six substantially triangular-shaped gemstones or diamonds, each having three side walls. The multi-stone round setting includes a curved corner prong assembly having six curved prong members; six side rail members connected to the six prong members to form a substantially round-shaped setting; a central support member having six connection points and six support ledges; and six radially extending spoke members connected at their outer ends to the six prong members, respectively, and connected at their inner ends to the six connection points, respectively, to form six seating areas. Each of the six seating areas are used for receiving one of six gemstones. Each of the six triangular-shaped gemstones include three side walls, three corners, and a bottom wall, respectively, and six grooves formed in the six bottom walls, respectively.

Abstract: The multi-stone setting for nine gemstones or diamonds includes a rectangular-shaped setting having a four-sided frame member with first and second parallel lower crossbars extending in a first direction and in the same plane, and first and second parallel upper crossbars extending in a second direction perpendicular to the first direction, and in a different plane. The first and second lower crossbars and the first and second upper crossbars form nine seats each for receiving one of nine gemstones or diamonds. The multi-stone setting includes four corners with four corner prongs mounted on the four corners, respectively. Each of the four corner prongs have a V-shaped configuration forming a right angle for engaging the four corner gemstones.

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.
