Disc-shaped diamond setting

Abstract

The present invention discloses a method for setting a disc-shaped diamond or other precious stone that provides increased stability and resistance to breakage, thus protecting the precious stone and minimizing the possibility that the setting may break or fail. The setting is accomplished by holding the disc-shaped stone onto an article of jewelry via a cap located on a distal end of a rod that extends through the center of the disc-shaped stone and is welded at a proximal end to a face of the article of jewelry. The disc-shaped stone is thus secured between the cap and the article of jewelry such that it is in contact with each, thereby preventing axial movement along the rod. These settings as described may be disposed at as many positions about an article of jewelry as so desired.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This patent application claims the benefit of priority, under 35 U.S.C. § 119, of U.S. Provisional Patent Application Ser. No. 60 / 973,417, filed Sep. 18, 2007, entitled “DISC SHAPED DIAMOND SETTING” the entire disclosure of which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention generally relates to jewelry, and more specifically to a method of setting a disc-shaped precious stone, such as a diamond, to an article of jewelry, such as a ring.BACKGROUND OF THE INVENTION[0003]Currently, jewelry settings are available in many different types and styles. Among the different sets or settings available are prong sets, bead sets, bezel sets, channel sets, pave settings, and invisible sets. These can be used alone or in combination with each other. There are certain disadvantages to each that the present invention addresses.[0004]Prong setting involves securing a stone between two to six wires (prongs), that ext...

AI Technical Summary

Benefits of technology

[0009]The present invention is directed to a jewelry setting for a disc-shaped stone, preferably a diamond or other precious stone, that addresses the problem of the stone becoming loose, and thus lost, due to settings that are susceptible to breakage or that do not adequately hold the stone in place. In the present invention, a cap located on a distal end of a rod secures a disc-shaped stone to an article of jewelry. The cap contacts the disc-shaped stone and is sized large enough to prevent the disc-shaped stone from dislodging. The rod extends downward from the cap through an aperture that is centrally located in the stone and also through an aperture located on an article of jewelry, such as a ring. The proximal end of rod is welded to the article of jewelry, thereby retaining the stone between the cap and the article of jewelry. In this way the disc-shaped stone retains contact with the cap and the article of jewelry at an upper and lower face, respectively, making it highly unlikely that the stone will become loose from the setting.

Problems solved by technology

These notches weaken the prong, and make it more likely to break.

However, both bead and pave settings are difficult to form and hide substantial portions of the stone.

Further, the beads may still wear down and can sometimes snag clothing.

As with other types of settings, the metal will wear down over time and the stone may loosen.

Pieces that are invisibly set are more fragile because there is not much metal used to hold the stones in place.

Thus, current setting techniques are susceptible to breakage or failure and thereby increasing the chances of losing a precious stone.
