Platinum rings


In most of the countries in which platinum jewellery is manufactured, it is made in a purity of at least 85 per cent platinum. Other platinum group metals - palladium, ruthenium and iridium - and copper and cobalt are commonly alloyed with platinum to optimise its working characteristics and wear properties.

Johnson Matthey Refining and Recycling accepts many forms of platinum, palladium and alloy jewellery scrap. 

Whether the scrap is from collected from rings, chains or rods or from lower grade sources such as floor sweeps, grindings or other residues, our refining facilities offer the highest standards and experience in evaluation, analysis, customer support and metal return to you.
