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.
