Rhodium Bars

Buy rhodium sponge in 1 oz, 5 oz and 10 oz, sealed as it leaves the refinery. Sponge is rhodium in its raw, finely divided form — the metal before anyone casts it into a bar — so you skip the fabrication cost and get more rhodium for the same money.

Shop Rhodium Sponge

• 1 oz rhodium sponge – the smallest sealed unit we stock.
• 5 oz rhodium sponge – a middle position without the 10 oz outlay.
• 10 oz rhodium sponge – the lowest premium per ounce, for buyers taking a real position.

What to Know Before You Buy

Sponge arrives sealed and should stay that way — the packaging carries the assay, and an opened unit is harder to sell on. If resale matters more to you than premium, a stamped rhodium bar is the better fit. Neither form is IRA-eligible; the IRS approves only gold, silver, platinum and palladium.

All rhodium sponge for sale here is priced live against a thin, volatile market rather than held at a fixed rate. Shipped fast, discreet and fully insured, and we buy rhodium back through Sell to Us.
