Semi-finished jewelry products

The basic materials used are alloys of Au and Ag in all lawful purities. We also offer our customers a wide range of Au and Ag chains and mechanisms of the corresponding colour, standard gold and silver blanks and rhodium baths, as well as surface rhodium plating.

Made of Au and Ag alloys in all lawful purities. Au alloys differ depending on the presence of other metals, which in turn affect, among other, their characteristic colouring - dark yellow, yellow, light yellow, white, pink, red, dark red or green. This also affects the mechanical properties of the alloy, in particular its hardness. Sheet metal is supplied either annealed or unannealed, as required. Rolled sheet metals are commonly produced in thicknesses that increase 0.1 mm at a time. Ag alloys, meanwhile, are mostly represented by sheet metals of 925/1000 purity and to a lesser extent, 935/1000 purity. Ag sheet metal can again be supplied annealed or unannealed in thicknesses that increase 0.1 mm at a time.
