Abstract
A prongless setting for mounting a gemstone and a method of manufacturing the same. The setting includes a base that is formed from a flat piece of metal, which is bent into the shape of a box having an open top. Two arcuate members are provided along the top edges of the box. A gemstone is placed into the open top of the box and the two arcuate members are bent over the top of the stone to retain it in the setting. Also, the method of stamping the blank that is suited for bending into the setting described above. Finally, forming a chain using a plurality of settings and gemstones that can be further incorporated into a finished piece of jewelry.
Claims18
A blank for forming a prongless gemstone setting, said blank comprising:
- a central body portion configured to receive a gemstone when formed into said gemstone setting,
- said central body portion including at least two opposing sides,
- each of said opposing sides including a terminal edge,
- each of said terminal edges including a bendable loop member having opposed first and second ends integrally formed with and respectively protruding from said terminal edge in a first normal non-retaining position substantially coplanar with said terminal edge which allows placement of a gemstone within the central body portion,
- each of said bendable loop members being configured to be bent relative to their respective terminal edges to a second overlying position to retain a gemstone within said central body portion when said blank is formed into said gemstone setting.
A prongless setting for a gemstone comprising:
- a base configured to receive a gemstone therein,
- said base including at least two opposing sides, each of said sides including a terminal edge;
- and
- at least two bendable loop members, each having opposed first and second ends which respectively protrude from a respective terminal edge in a first normal non-retaining position substantially coplanar with said terminal edge which allows placement of a gemstone within the base,
- said bendable loop members being bendable relative to said base to a second overlying position to retain a gemstone within said base.
An article of jewelry comprising:
- a prongless setting for a gemstone including
- a base configured to receive a gemstone therein, said base including at least two opposing sides, each of said sides including a terminal edge;
- and
- at least two bendable loop members, each having opposed first and second ends which respectively protrude from a respective terminal edge of said base said bendable loop members each having a first normal non-retaining position substantially coplanar with said terminal edge which allows placement of a gemstone within the base;
- and
- a gemstone received in said base of said prongless setting between said at least two bendable loop members,
- said at least two bendable loop members being bent inwardly and downwardly to a second overlying position over a top portion of said gemstone to retain said gemstone in assembled relation with said base.
A prongless jewelry chain comprising:
- a plurality of prongless gemstone settings,
- each of said prongless gemstone settings individually comprising a base configured to receive a gemstone therein, each of said bases including at least two opposing sides, each of said sides including a terminal edge, each of said prongless gemstone settings further including at least two bendable loop members, each loop member having opposed first and second ends which respectively protrude from a respective terminal edge of each of said bases, each of said prongless gemstone settings still further including a gemstone received in each of said bases between said at least two bendable loop members, said at least two bendable loop members being bent inwardly and downwardly over a top portion of said gemstone to retain said gemstone in assembled relation with each of said bases;
- and
- a plurality of link elements sequentially connecting adjacent ones of said plurality of prongless gemstone settings to form a continuous jewelry chain.
