Benefits of technology

[0015] The present invention presents a novel, unique and improved setting for diamonds or diamond shaped stones that not only can hold diamonds or diamond shaped stones of different sizes, but also fits the most common and preferred culet angle of diamonds or diamond shaped stones, so that no undesirable space is visible under the culet of the diamonds or diamond shaped stones, and the diamond or diamond shaped stone is always held in a right orientation. OBJECTS OF THE PRESENT INVENTION
[0025] It is a still further object of the present invention to provide a setting that can be easily used by jewelers for setting diamonds or diamond shaped stones.

Problems solved by technology

The problem with the Butler setting, however, is that the oblique angle of the prongs does not match the most common and preferred culet angle of diamonds or diamond shaped stones.
The appearance of such empty space is often undesirable.
In addition, because the oblique angle of the prongs in the Butler setting does not match the oblique angle of the sidewall of the pavilion of most diamonds or diamond shaped stones, the prongs of the setting do not abut or support the pavilion of the diamond or diamond shaped stone held by setting, which increases the risk that the diamond or diamond shaped stones is not set straight but with a tilted angle relative to the symmetric axis of the setting, which also results in an undesirable appearance.

Embodiment Construction

[0039] Referring to FIGS. 3 and 4, one of the preferred embodiments of the present invention setting for diamonds or diamond shaped stones is shown and generally referred to by the numeral 30. In the following descriptions, the word “diamond(s)” will be used to indicate both diamond(s) and diamond shaped stone(s).

[0040] The setting 30 has three prongs 32 generally made of metal or other similar materials. The prongs 32 are joined at their bottom ends to form bottom joint 34 which serves as the base of the setting 30. The prongs 32 extend upwardly and outwardly from the bottom joint 34, and are disposed spaced apart symmetrically about a symmetric axis X of the setting 30, i.e., the angle A between each prong 32 and the axis X is the same, and the angle B between any two adjacent prongs 32 is also the same for all three prongs 32.

[0041] One of the most important novel and unique features of the present invention setting 30 is the oblique angle A of its prongs 32. As discussed earli...

Abstract

A setting for a diamond or diamond shaped stone is disclosed which can be used for setting any sized diamond or diamond shaped stone. The setting consists of a series of prongs that are angled to match the most common and preferred culet angle of all diamonds or diamond shaped stones, which is approximately 98°. The prongs are of a length longer than the length of the sidewall of the pavilion of the diamond or diamond shaped stone and the portion of the prongs beyond the size needed is cut off and their ends deformed to hold the diamond or diamond shaped stone.

Description

[0001] This is a regular patent application based on U.S. Provisional Patent Application No. 60 / 534,585 filed on Jan. 5, 2004.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention is directed a setting for diamonds or diamond shaped stones that has extended prongs for holding a diamond or diamond shaped stone and is adapted for use with various sized diamonds or diamond shaped stones, where the excess length of the prong is cut off to form a holding end to hold the diamond or diamond shaped stone. [0004] 2. Description of the Related Art [0005] Settings with extended prongs for mounting diamonds or diamond shaped stores have been used in the past, which typically have several metal prongs upwardly and outwardly extending from a bottom joint or base. The prongs are generally symmetrically arranged about a central symmetric axis of the setting. [0006] One example of the prior art settings for diamonds or diamond shaped stones is shown in U.S. Pat. N...
