Abstract

A novel technique for setting a multiplicity of precious stones such as diamonds into a unique setting to enhance the beauty and presentation of the multiplicity of set stones, with the technique including setting a center stone into a socket and having it held by a multiplicity of prongs, an outer series of small stones wherein each outer stone is respectively placed in a socket and is held in most designs by a pair of the same prongs which hold the center stone and is also held by a lower groove in the interior facing surface of the outer wall, and an intermediate series of stones which are placed in a respective socket and are held by a pair of the prongs which also retain the center stone and in most designs all of the smaller stones and are also retained by a groove in the interior facing surface of the outer wall, the intermediate series of stones also serving to retain the small series of stones.

Dependent claims

A technique for setting precious stones in a round shaped mounting comprising:

a. starting with a round shaped mounting having a round shaped exterior wall including an interior surface and a floor with a multiplicity of sockets therein including a center socket, a multiplicity of outer sockets and a multiplicity of intermediate sockets, wherein a portion of each outer socket extends into a lower channel in the interior surface of the outer wall and a portion of each intermediate socket is adjacent the interior surface of the outer wall, the outer sockets being positioned below the intermediate sockets with each outer socket positioned between two intermediate sockets and each intermediate socket positioned between two outer sockets, and a multiplicity of frustum shaped prongs positioned around the center socket;
b. positioning a multiplicity of outer stones each having a pavilion and a girdle in the outer sockets so that a respective outer stone is placed in a respective outer socket such that its pavilion is placed in the socket and a portion of its girdle is placed into and partially retained by the lower channel in the interior surface of the outer wall, each outer stone also partially retained by a frustum shaped prong;
c. positioning a center stone having a pavilion and a girdle in the center socket so that the pavilion is placed in the center socket and the multiplicity of frustum shaped prongs hold the center stone by its girdle;
d. positioning a multiplicity of intermediate stones each having a pavilion and a girdle in the intermediate sockets so that a respective intermediate stone is placed in a respective intermediate socket such that its pavilion is placed in the socket and a portion of its girdle is placed into and retained by an upper channel in the interior surface of the outer wall, each intermediate stone also partially retained by a pair of frustum shaped prongs such that each intermediate stone partially overlaps the center stone and also partially overlaps a pair of outer stones to thereby partially retain a pair of outer stones;
and
e. the outer wall further comprises an outer surface which is surrounded by a bezel having a multiplicity of stones retained in the bezel, each stone retained by a pair of oppositely disposed prongs.
