Buy 1 oz Rhodium Sponge

This is the most liquid form of physical rhodium. Pure rhodium, viewed magnified, appears porous and powdery. This is why it is known as “sponge” in industry parlance. 

Kitco Rhodium Sponge is a Kitco-exclusive product: Pure rhodium powder (.999+ fine) packaged in tough, tamper-proof pharmaceutical-grade plastic bottles. In addition to a unique serial number, each bottle’s label bears indications of its contents’ net weight and purity. As with bars, you can own this most rare precious metal outright. 

Unlock an exclusive opportunity to own rhodium sponge. While the choice is entirely yours, we highly recommend our  Kitco Allocated Storage program to maintain its integrity within our trusted chain. By choosing our storage, you'll secure the full current bid price and avoid any additional assay costs when you decide to sell in the future.
