Definitions
- the invention relates to a piece of jewelry, such as a piece of jewelry, in particular a ring-shaped piece of jewelry, a part of a piece of jewelry or a semi-finished product for the production of a piece of jewelry according to the preamble of claim 1, a jewelry alloy for the production of such a piece of jewelry and a method for producing the jewelry -Alloy.
- the jewelery body is made from a gold alloy with a proportion of copper.
- DE60310555T2 discloses an alloy for the production of watches, jewelery and jewellery, which has a gold content of at least 75% by weight and a copper content of at least 14% by weight. It is also described how a hue from red to pink to yellow can be achieved in gold alloys of this type, depending on the proportions of copper and silver.
- JP2005082890A discloses a gold alloy which, in addition to the main proportion of gold, has a copper proportion of 18 to 20% by weight, a silver proportion of 2 to 5% by weight, a palladium proportion of 1.5 to 2.5% by weight and a Zinc content of 0.4 to 0.6 wt .-%.
- the alloy creates a pink-based hue.
- the object of the invention is to provide a new coloring for a generic piece of jewelry and to ensure good workability, such as in the continuous casting process.
- This object is achieved by the jewelery body made from a copper-containing gold alloy with the features of claim 1.
- the gold alloy consists of at least 75.0 to a maximum of 75.2% by weight gold, at least 16.5 to a maximum of 17.0% by weight copper, at least 3.1 to a maximum of 7.1% by weight silver, at least 1.2 to a maximum of 3.2% by weight of palladium and a remainder containing at least 0.5 to a maximum of 2.5% by weight of zinc, whereby a piece of jewelry with a new color tone is obtained, which is referred to as champagne-colored can.
- the alloy consists of at least 75.0 to a maximum of 75.2% by weight, in particular 75.1% by weight gold, 16.5 to 17.0% by weight copper, 3.1 to 7.1% by weight silver, 1.2 to 3.2% by weight palladium, and a remainder containing between 0.8 and 1.1% by weight zinc.
- a particularly intense champagne color can be achieved and particularly good workability of the gold-copper alloy can be guaranteed.
- the above object is achieved by a method in which the zinc content of the alloy is at least partially obtained by melting brass together with the other components. In this way, the zinc content of the melt can be produced particularly easily.
- the brass melted in here is advantageously formed by Cu63Zn37 brass, as a result of which the desired proportion of zinc can be melted in particularly easily and in an exact quantity.
- the melt can be fed to a continuous casting process, in particular in the case of larger quantities, in order to be able to produce semi-finished products, for example, which can be used for subsequent further processing
- Can serve jewelry such as for the production of fully or partially champagne-colored jewelry rings.
- a preferred composition of the melt for the production of the jewelery alloy and the jewelery body with a particularly radiant champagne color is given below:
