ABSTRACT:
A jewelry article basically comprises a plurality of large round diamonds and small round diamonds with the pavilion portion of the large round diamonds bearing directly upon and overlying, at least a portion, of the crown of the smaller round diamonds such that individually metallic prongs for the diamonds are eliminated. In this manner, the overall brilliance of the structure is increased, greater continuous diamond surface is exposed, less total carat weight is required to provide the same size ring as would be required with individual prong settings and, correspondingly, the cost of the ring structure is decreased.
