ABSTRACT:
FIELD OF THE INVENTION
The present relates to a multi-stone center setting for holding therein nine (9) or twelve (12) rectangular-shaped or square-shaped gemstones (princess cut gemstones) in which the combined gemstone aggregate gives a larger appearance than that of a single gemstone of a similar carat weight. More particularly, this multi-stone center setting having nine to twelve gemstones therein gives the appearance that the setting is substantially invisible.
BACKGROUND OF THE INVENTION
Invisible gemstone settings are well known in the art and refers to a setting for gemstones in which the setting lies beneath the visible surface of the gemstones. Typically, to invisibly set a large number of gemstones, the approach of the prior art has been to notch the gemstones and to mount them in a setting having two or more parallel walls, with metallic projections, for example, prongs or the like, protruding from these walls for engaging the notches. Generally, these walls define channels in which the gemstones are set abutting one another in accordance with the invisible mounting method.
Invisible gemstone settings for jewelry products suffer from a number of disadvantages. First, casting of a jewelry item with a gemstone region including a recess and walls and preparing T-shaped cross bars is a relatively difficult and therefore costly process. Second, the assembly of the jewelry item requires considerable time of a skilled worker which adds greatly to the overall cost of the jewelry item. And third, the finished jewelry item cannot be readily downsized without disturbing the invisible gemstone setting.
Therefore, there remains a need for a novel invisible and multiple gemstone setting for jewelry ornaments which overcomes the disadvantages of conventional multi-stone and invisible gemstone settings for jewelry items. The multi-stone center setting would include a rectangular-shaped or square-shaped metal setting for holding nine to twelve princess cut gemstones in which the combined gemstone aggregate gives a larger appearance than that of a single gemstone of a similar carat weight. Additionally, the multi-stone center setting would give the appearance that the setting (metal) is essentially invisible to the eye of the wearer.
DESCRIPTION OF THE PRIOR ART
Invisible gemstone settings, multi-gemstone settings, jewelry settings and the like having various designs, structures, configurations and functions have been disclosed in the prior art. For example, U.S. Pat. No. 5,848,539 to OUZOUNIAN discloses an invisible, multiple precious stone setting for mounting two or more rows of round-shaped precious stones. This prior art patent does not disclose the structure and configuration of the present invention.
U.S. Pat. No. 5,520,017 to VIVAT discloses jewelry items with invisible gemstone settings, wherein the gemstone setting includes a least two walls so as to provide at least one groove. The groove slidably receives one or more rectangularly-shaped precious stones therein. This prior art patent does not disclose the structure and configuration of the present invention.
U.S. Pat. No. 5,123,265 to RAMOT discloses an invisible gemstone setting, wherein the gemstone setting assembly includes one or more gemstones and a setting having a base formed with a plurality of ribs defining one or more sockets of polygonal configuration for receiving the gemstones. This prior art patent does not disclose the structure and configuration of the present invention.
U.S. Design Pat. No. D403,611 to LAI discloses an ornamental design for a jewelry setting having a square-shaped grid pattern for square-shaped gemstones. This prior art patent does not disclose the structure and configuration of the present invention.
None of the aforementioned prior art patents disclose or teach the multi-stone center setting of the present invention for receiving therein nine or twelve rectangular-shaped or square-shaped gemstones which gives the appearance of a single gemstone by essentially giving the setting an invisible profile.
Accordingly, it is an object of the present invention to provide a multi-stone setting for holding therein nine or twelve rectangular-shaped or square-shaped gemstones in which the combined aggregate of the nine or twelve gemstones give a larger appearance than that of a single gemstone of a similar carat weight (i.e., a 2.4 carat presentation of the combined nine or twelve gemstones appears as large as a 4.0 carat gemstone, as the present invention would have a larger table).
Another object of the present invention is to provide a multi-stone setting having nine or twelve gemstones therein that is less expensive than a single gemstone of a similar carat weight (i.e., the 2.4 carat presentation of the combined nine or twelve gem-stones is less expensive than an actual 2.4 carat single gemstone of the same carat weight).
Another object of the present invention is to provide a multi-stone setting having nine or twelve princess cut gemstones therein which gives the appearance that the setting is substantially invisible at distances greater than 12 inches from the jewelry product.
Another object of the present invention is to provide a multi-stone setting that can be varied in size depending upon the total combined carat weight of the nine or twelve gemstones within the setting.
Another object of the present invention is to provide a multi-stone setting that can be made from precious metals such as gold, silver, platinum or palladium for setting precious gemstones including diamonds, rubies, sapphires, emeralds and the like.
Another object of the present invention is to provide a multi-stone setting having nine or twelve gemstones therein for use in personal adornment in the form of ornamental jewelry such as rings, pins, brooches, pendants, clasps, necklaces, bracelets, anklets and earrings.
Another object of the present invention is to provide a multi-stone setting that can be produced in an economical manner and is readily affordable by the jewelry consumer.
SUMMARY OF THE INVENTION
In accordance with the preferred embodiment of the present invention, there is provided a multi-stone setting having nine gemstones or diamonds. The multi-stone setting includes a rectangular-shaped setting having a four-sided frame member with a first lower crossbar extending in a first direction and a second lower crossbar being parallel and in the same plane to the first lower crossbar and also extending in the first direction.
The rectangular-shaped setting also has a first upper crossbar having first insert tabs extending in a second direction perpendicular to the first direction and a second upper crossbar having second insert tabs being parallel and in the same plane to the first upper crossbar and also extending in the second direction. The first and second lower crossbars are located in a different plane than the first and second upper crossbars.
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 first and second lower crossbars and the first and second upper crossbars define two outer rows of seats to form six outer seats and one inner row of three seats for receiving the nine gemstones, in order to form a first outer row of gemstones, a second outer row of gemstones, and an inner row of gemstones, and the first and second outer rows of gemstones forming four outer gemstones, each of the four outer gemstones having side walls.
The first outer row of gemstones include a first set of inner side walls for engaging the first upper crossbar, the first set of inner side walls has grooves formed therein for seating the first outer row of gemstones on the first insert tabs of the first upper crossbar.
The second outer row of gemstones include a second set of inner side walls for engaging the second upper crossbar, the second set of inner side walls has grooves formed therein for seating the second outer row of gemstones on the second insert tabs of the second upper crossbar.
The inner row of gemstones include
