Description

Detailed Description of the Invention

This invention is a white gold alloy for jewelry that contains gold as a main component, and gold is a gold alloy of 75 to 88% by weight or more, and 0.1 to 2.0% by weight of germanium and the balance is composed of palladium. In spite of being a gold alloy, its color is white that is not inferior to platinum, and it is a white gold alloy that has excellent workability and extensibility, and excellent hardness during processing. To do.

The present invention relates to a white gold alloy for jewelry having gold as a main constituent, and a jewelry using the same.

For example, gold alloys mainly composed of gold are mainly used for jewelry. A gold alloy of 75% by weight of gold, 12.5% by weight of silver and 12.5% by weight of copper is used as a so-called 18 gold in jewelry.

As the gold material used for the gold alloy for the jewelry as described above, JP-A-10-60556, JP-A-10-60558, JP-A-9-209059, JP-A-9-209060, JP-A-7- As seen in No. 70671 and the like, various trace components are blended to increase the hardness and surface strength.

The invention's effect

According to the present invention, it is possible to realize a white gold alloy having both a decorative function and a health-oriented function, and a jewelry using the same. In particular, the jewelry of the present invention has an improvement in workability and extensibility that is almost the same as that of 18K gold, realization of a white gold alloy jewelry whose color is not inferior to platinum, health promotion and therapeutic effect by the far infrared effect. Can be realized simultaneously.

Problems to be solved by the invention

Each of the above prior arts contains silver, copper, germanium, or cadmium as a main component of gold, and each has suitability for a general accessory.

However, the conventional gold alloys for general accessories have the following problems. First, since it contains silver, copper or cadmium, the hardness is high, the ductility is inferior, and the material is unstable.

In addition, as for jewelry, it is mainly intended to wear aesthetic body decorations such as rings and earrings, or to wear articles having a specific function (watch body) such as wristwatch belts on the body. In addition to the intended ones, there are known health-oriented accessories that have a secondary or primary purpose of promoting health and providing certain treatment and healing effects.

However, the conventional jewelry taking such health and treatment into consideration contains germanium as a main component, which is different from the above-mentioned decorative object having gold as a main component. For example, in the one described in Japanese Examined Patent Publication No. 58-48186, a solid piece of N-type, intrinsic or P-type germanium is brought into contact with the skin with a member such as a tape, and analgesia is caused by electrical action. It is said that it can be extinguished.

In addition to the above-described conventional techniques, various studies have been made on gold alloys. Gold alloys that are particularly suitable for jewelry that is used in contact with the skin and that is expected to promote health and other effects. Has not been provided yet. That is, a far-infrared effect of germanium, that is, a gold alloy that pays attention to the fact that germanium can exhibit a health promotion and therapeutic effect for treating and healing shoulder stiffness and the like has not been provided.

Therefore, as a result of repeated studies, the present inventors have invented a novel platinum-colored and incomparable white gold alloy for jewelry that is suitable as a constituent material for jewelry that has a decorative function and health promotion or treatment / healing function.

The invention's effect

According to the present invention, it is possible to realize a white gold alloy having both a decorative function and a health-oriented function, and a jewelry using the same. In particular, the jewelry of the present invention is a white gold alloy that is inferior to platinum in color, has high workability compared to conventional alloys for jewelry, and simultaneously realizes health enhancement and therapeutic effects due to the far-infrared effect. Is possible.
