Abstract

<P>PROBLEM TO BE SOLVED: To provide a new material for an accessory, which is suitable for a material for composing an accessory having both a decoration function and a health-enhancing function or curing and healing functions. <P>SOLUTION: The gold alloy comprises 0.1-2 wt.% germanium and the balance gold. The gold alloy can provide the accessory which has metallic luster equivalent to the luminance of high-purity gold, superior ductility and workability, and simultaneously develops effects of health enhancement and medical treatment due to a far infrared effect. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

Detailed Description of the Invention

This invention is a high-grade gold alloy for jewelry having gold as a main component, and gold is a gold alloy of 98 to 99.9% by weight or more, and 0.1 to 2.0% by weight of germanium in the balance. By being contained, it is a high-grade gold alloy that is excellent in workability and ductility while being a high-grade gold alloy and excellent in hardness during processing.

The present invention relates to a 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 high-grade gold alloy having both a decoration function and a health-oriented function, and a jewelry using the same. In particular, the jewelry of the present invention can realize high-grade gold alloy jewelry, health enhancement by the far-infrared effect, and therapeutic effect at the same time by improving workability and extensibility almost the same as 18K gold. become.

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.

Thus, as a result of repeated studies, the present inventors have invented a novel high-purity gold alloy for jewelry suitable for a constituent material for jewelry having both 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 high-grade gold alloy having both a decoration function and a health-oriented function, and a jewelry using the same. In particular, the jewelry of the present invention has a high quality value due to the high purity of gold, has high workability compared to conventional high-purity gold for jewelry, and at the same time realizes health enhancement and therapeutic effects due to the far-infrared effect. Is possible.

Claims (2)

A high-grade gold alloy for jewelry, characterized by comprising 0.1 to 2.0% by weight of germanium and the balance being gold. A clothing accessory characterized in that an outer surface that comes into contact with the skin when worn on the body is composed of the gold alloy for clothing accessory according to claim 1.
