Round gemstone arrangements with settings

Abstract

In accordance with the present invention, there is provided a multi-stone setting for receiving four substantially triangular-shaped gemstones or diamonds in the round setting. The multi-stone round setting includes a prong assembly having four prong members; and one or more curved side rail members connected to the four prong members to form a round-shaped setting. The multi-stone round setting also includes a first center crossbar member connected at the ends thereof to two opposed curved side rail members and a second center crossbar member being perpendicular to the first center crossbar member; wherein the second center crossbar member is connected at the ends thereof to the other two opposed curved side rail members for forming four seating areas. The first center crossbar member includes first and second retaining edge insert members. The four seating areas are each used for receiving one of the four gemstones or diamonds therein. The four triangular-shaped gemstones or diamonds each have two side walls and a curved outerwall and three corners, respectively; and each of the four triangular-shaped gemstones or diamonds have at least one of the side walls with a groove formed therein for engaging the first or second insert means of the center crossbar member for seating two of the four triangular-shaped gemstones or diamonds within each of the four seating areas and for supporting the four gemstones or diamonds in the four seating areas. Each of the four prong members are used for engaging the gemstones in order to keep the four gemstones or diamonds seated within the four seating areas of the multi-stone round setting.
