ABSTRACT:
A ring has two zig-zag interior sidewalls and two opposite exterior sidewalls, where the walls form three parallel channels each receiving one of the rows of precious stones. Each interior sidewall has alternating inward and outward facing protruding projections extending into the channels, and each exterior sidewall has multiple small inward facing recesses. The alternative inward-facing protruding projections of one zig-zag sidewall are respectively paired with the alternative inward-facing protruding projections of the other zig-zag sidewall. The alternative outward-facing protruding projections of each zig-zag sidewall are paired with the small inward facing recesses of the respective adjacent exterior sidewall. The stones of the middle row have cutout grooves on both sides of each stone. The stones of the two outside rows have a cutout groove on only one side of each stone. The stones of the middle row are secured and held between the two zig-zag sidewalls, where the paired protruding flanges are engaged with the two cutout grooves at both sides of each stone. The stones of each outside row are secured and held between an interior sidewall and an adjacent exterior sidewall, where the outward-facing protruding projections of the interior sidewall are engaged with the cutout groove at one side of a respective stone, and the other side of the diamond without any cutout groove is engaged with the inward-facing dent of the exterior sidewall.
