Rhodium is increasingly used in the jewellery manufacturing for decoration purposes or as the protection coating of precious metal. Pure rhodium jewellery is not produced, due to its high cost and difficulty of fabrication. Silvery white rhodium is the one generally used in jewelcrafting, however it can be black or coloured.
Rhodium is hypoallergenic, threfore the metal is suitable for everyone.
Pieces of jewellery are getting coated with a thin layer of rhodium, which gives them a silvery-white colour, with a cool, bluish tint. For instance, white gold is not always perfectly white, and it may have yellowish or even pinkish hue, and to avoid it, white gold jewellery gets rhodium plated. After such treatment, the product acquires an attractive, glossy luster.
Over time, sterling silver may oxidise and tarnish. Rhodium plating helps avoid this, however, such jewellery is higher in price.
Rhodium plating is extremely popular as a decorative element. White rhodium plated stone settings enhance diamond and cubic zirconia radiance, allowing them to look brighter. Red or yellow gold jewellery, featuring partial rodium plating, showcase stylish, contrasting combination of colours.
Despite its unique properties and hardness, rhodium is a subject to wear and requires renovation. It is difficult to say how long the coating will last on a particular product, as there are many factors affecting that, such as frequent skin contact, interaction with chemicals and so on.
