Rhodium Plating
Rhodium plating has been widely applied to semi-jewelry with the objective of granting greater durability to pieces. Rhodium (RH) is a metal from the platinum family.
Rhodium plating coats the metal with a protective layer, making it more resistant to stains and scratches. Moreover, it is very shiny, and this quality has an important aesthetic value, since the jewelry (or semi-jewelry) becomes much more beautiful after this plating. Shine and resistance are two adjectives commonly used to designate rhodium.
Rhodium Plating Applications
Rhodium plating can be done galvanically in full on a piece of jewelry or on specific parts using a pen coating system, called Rhodium Applique.
Curiosities
Where is rhodium found in nature?
The earth's crust contains only 0.001 ppm*, or 0.0000001%, of rhodium. Rhodium is found mainly in nature in its pure form, always consists of a stable isotope (103Rh) and will always be found with other platinum group metals. Minerals that contain rhodium include cuprorhodsite, cherepanovite, polkanovite and miassite. The largest mines are in South Africa and the Ural Mountains, and both are platinum group mines. Other deposits are found in South America. In Canada, it is found in nickel minerals.
