Electrolytes for costume jewellery and luxury jewellery

Are you looking for electrolytes for the surfaces of costume jewellery and luxury jewellery? Brilliant sparkling finishing layers are popular worldwide – we serve you with a carefully arranged variety of electrolytes for noble surfaces, by the way, also for timepieces.

Currently, our new top product RHODUNA® Diamond Bright is particularly trendy. Worldwide, it arouses astonishment with gleaming white surfaces, which are more brilliant than previously known on the market.



AURUNA® 502 is a neutral, cadmium-free gold copper electrolyte working without free cyanide. The red surfaces are bright, very hard and abrasion-resistant.



RHODUNA® Alloy is the first alloy electrolyte in the world combining the high-quality metals rhodium and ruthenium. The basic materials of the new coating are truly royal: A mixture of rhodium, one of the world‘s most valuable precious metal, and the platinum group metal ruthenium.

Its white colour is absolutely equivalent to that of a pure rhodium layer. The electrolyte has all the quality characteristics of high-grade rhodium coatings and surpasses them in durability and uniformity.

RHODUNA® 470 Black adds a superior final layer to jewellery with a thickness up to 0.3 μm. The layer persuades with good corrosion resistance. The electrolyte is perfectly suited for applications where black ruthenium cannot fulfill the requested abrasion requirements.
