Description
J. c. LINK GEM SETTING Nov. 28, 1939.
Filed Aug. 9, 1939 VENTOR y BY 1: 1 g ATTORNEY Patented Nov. 28, 1939 --=--UNITED STATES T,PAT;EN; FICE GEM SETTING Julius 0. Link, Brooklyn, N. Y. Application August 9, 1939, Serial No. 289,101
Claims.
metal foil becoming tarnished by dust, dirt or the like, it becomes diflicult to clean the same to restore it brilliancy and the effect of the metal foil is thus destroyed. For this reason, the diamond chips were considered of little value, and the extensive use of the chips has been restricted.
The primary object of this invention is to provide a mounting for rose diamonds or diamond chips, in which the use of reflecting metal foil or the like can be dispensed with, and in which said mounting is provided with reflecting surfaces which can be readily and. easily cleaned when desired.
A further object of the invention is to provide a mounting with a reflecting surface which greatly extends the fleld of use of such diamonds or diamond chips, particularly in the provision of high-cost jewelry, as well as in the provision of low-cost-jewelry.
A further object of the invention is the provision of a setting for diamonds or diamond r chips in which the reflecting surfaces are in the form of a pyramid with the diamond preferably resting upon the apex of the pyramid, thus providing a plurality of reflecting surfaces for directing the light on the underside of the stone,
4 thereby increasing the brilliancy and lustre thereof.
These and other advantageous objects, which will later appear, are accomplished by the simple and practical construction and arrangement of parts hereinafter described and exhibited in the Fig. 4. is a side elevational view of a finger ring having settings embodying my invention,
Fig. 5 is a top plan view of the, setting,
Fig. 6 is a bottom plan view of the setting,
Fig. 7 is a sectional view taken on line l-'| of 6 Fig. 5, and Y Fig. 8 is a side elevational view of the setting.
Referring to .the drawing, there is shown a setting comprising a base I0 from which projects a four-sided pyramid l I, providing four reflecting surfaces. Extending upwardly from the base 10 are four prongs l2 which have the upper surfaces thereof provided with notches 13 to facilitate the upsetting of portions of the prongs over the girdle of a diamond or other stone M to hold it rigidly in the setting.
A rose diamond is relatively thin and has a flat under surface, which, when mounted in the above described setting, preferably rests upon the apex of the pyramid II, the prongs l2 being upset over the upper surface of the diamond.
It will be seen that the sides of the pyramid effectively reflect light upwardly through the undersurface of the diamond and increases the brilliancy thereof. Also, should the setting lose some of its brilliancy and lustre due to its being 25 subjected to dirt, dust or the like, it can be readily cleaned, as the parts subjected to the dirt and dust are conveniently accessible.
' By means of the setting herein described, the field of use of rose diamonds, that is, diamond chips, may be extended; and it is now possible to produce articles of jewelry with rose diamonds to attain an effect similar to that attained by using a properly cut diamond. The operation of mounting a stone in the setting obviously is 35 simple, and at the same time the stone is rigidly and securely mounted in the setting. I
The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as restrictive or limitative of the invention of which obviously, embodiments may be constructed, including many modifications, without departing from the spirit and scope of the invention herein set forth and denoted in the appended claims.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
1. In a gem setting, a base having a pyramid projecting upwardly therefrom, the apex of said 50 pyramidbeing in close proximity to a stone, and prongs projecting upwardly from the base, said prongs being adapted to receive a stone.
2. In a gem setting, a base having a four-sided pyramid projecting upwardly therefrom, the apex the apex of the pyramid.
3. In a gem setting, a base having a plurality of flat inclined upper reflecting surfaces and provided at the center thereof with means to receive the flat surface of a stone, and prongs projecting upwardly from the base to engage a stone.
4. In a gem setting, a base having a four-sided pyramid projecting upwardly therefrom, and prongs projecting upwardly from the four corners of the base of the pyramid, said prongs being adapted to engage a stone resting upon the apex of the pyramid.
5. In a gem setting, a base having projecting upwardly therefrom a pyramid with a plurality of inclined reflecting surfaces, and a plurality of prongs projecting upwardly from the corners of the base of the pyramid, said prongs being adapted to engage a stone resting upon the apex of the pyramid.
