A beautiful silvery white metal from the platinum group, rhodium is one of the most expensive of all the precious metals. It is most often used in catalytic converters in car exhausts, and in the jewelry industry. This element's name is derived from the Greek for 'rose' owing to the deep red colour of the compound it was discovered in. This Elemental Cat is all done up in a white and pink colour scheme with a dark red rose bloom to honour its name.
