A simple pendant that holds the metal in place.

Abstract

To ensure aesthetic appeal, we polish gemstones to a high yield and reduce the weight of the metal by directly attaching them to the bail, thereby providing economically competitive jewelry. [Solution] Transparent gemstone crystals, which are normally considered to have a low yield, are polished while preserving their natural shape. The crown of the gemstone is made into a cabochon 4, and the pavilion of the gemstone is made into a rose cut 5. A 0.5 mm hole 6 is drilled at the attachment position of the bail 2, and a 0.3 mm diameter wire 7 is passed through this hole and the 0.4 mm hole in the bail to attach it.

Description

Technical Field

[0001] This invention is a pendant processing technology specialized in reducing the amount of base metal used for gems with a hardness of 7 or more, strong toughness, and high transparency.

Background Art

[0002] Due to the soaring prices of gold, platinum, and natural gems, in the low-price jewelry market, jewelry using K18 or Pt900 has lost its economic competitiveness. Also, the amount of rough stones that can be polished into gems of 1 carat or more is decreasing.

Summary of the Invention

[0004] Conventional pendants attach the gem on the base metal setting and attach the bale. Therefore, a 1-carat gem pendant requires more than 1 gram of base metal. Furthermore, since the gem is cut into shapes such as oval, round, and drop, and facets are added to the crown and pavilion, the yield from rough stones is said to be about 20 - 40%. Therefore, in order not to impair the aesthetic quality, it is intended to polish the gem into a shape with a good yield, remove the setting, and directly attach the bale to this gem to solve the above problems. Means for Solving the Problems

[0005] This invention utilizes the natural shape of flat crystals, which inherently have a poor yield, by polishing the crown (upper part of the gemstone) into a gentle cabochon and the pavilion (lower part of the gemstone) into a rose cut, ensuring safety even when in direct contact with the skin. A 0.5mm diameter hole is drilled in the narrower end, and a 0.3mm diameter wire is passed through it to attach the bail. This allows the bail and gemstone to move smoothly, and furthermore, the hole and wire are not visible from the front, solving the problem.

[0006] This invention's gem polishing method improves the yield from the crystal and the apparent density, and because it polishes flat crystals, the appearance appears about 30% larger. In addition, by eliminating the setting, the weight of the metal (K18 / Pt900) is reduced to about 0.20g, which helps restore economic competitiveness. [Brief explanation of the drawing]

[0007] [Figure 1] This is a front view showing one embodiment of a simple pendant that holds the base metal of the present invention. [Figure 2] This is a side view of one embodiment of this pendant. [Figure 3] This is a magnified cross-sectional view of the Vatican section. [Figure 4] These are the front and back views of the new cut. [Modes for carrying out the invention]

[0008] The gemstone used in this design is natural sapphire, but since it will be used as a loose stone after drilling, a flat, transparent crystal with a hardness of 7 or higher, good toughness, and not a popular choice is ideal. To increase the yield, the crystal is cut into a drop shape that takes advantage of its natural form, the crown is polished into a smooth cabochon, and the pavilion into a rose cut, with a 0.5mm diameter hole drilled into the narrower end. A 0.3mm wire is passed through this hole and a bail is attached, so the small hole allows for greater design freedom for the bail, resulting in a pendant where the gemstone and bail are integrated. [Examples]

[0009] An embodiment will be described below with reference to the attached drawings. 1 is the new cut gemstone body, which improves the yield from the crystal and makes the color appear richer. 4 is the top of the cabochon-cut gemstone, 5 is the bottom of the rose-cut gemstone, 6 is the 0.5mm diameter hole in the gemstone, which is a characteristic of the new cut, 2 is the bail, and a 0.3mm diameter wire 7 is passed through the 0.4mm diameter hole in the bail 8 and the hole in the gemstone 6 and welded to the bail, thereby completing the direct-attached gemstone pendant.

Claims

1. A piece of jewelry in which a bail is directly attached to a transparent gemstone, resulting in a piece where the bail and gemstone are integrated into one.

2. Flat crystals of tough, transparent gemstones with a hardness of 7 or higher, which were previously considered to have a low yield, are polished to preserve their natural shape, with the crown cut into a cabochon and the pavilion into a rose cut, making the external color appear richer and the gemstone appear larger. This new cut is characterized by the use of gemstones with a small 0.5 mm hole drilled in the bail attachment area.

3. By passing a 0.3 mm wire through the hole in the gemstone and the 0.4 mm diameter hole in the bail and welding it, only about 0.2 g of metal (K18 / Pt900) is needed, the hole and shaft are not visible from the front, the gemstone moves smoothly, and the piece of jewelry has the advantage of being aesthetically pleasing.

4. An ornament characterized by its high economic competitiveness, which integrates a Vatican and a gemstone, as formed by the configuration of Claim 2 and Claim 3.
