Five troy ounces of .999 fine rhodium, sealed as it left the refinery. The middle unit in our sponge range: a real position in the rarest of the precious metals without the outlay of ten ounces. Priced live against the market, shipped fully insured.
Buy 5 oz rhodium sponge in a single sealed unit — five troy ounces of .999 fine rhodium, priced closer to the metal than any minted bar of the same weight. This is the middle unit in our sponge range, and for most buyers it is the point where rhodium stops being a curiosity and becomes an actual position.
What You’re Buying
- Weight – 5 troy oz (155.52 g) of rhodium.
- Purity – .999 fine.
- Form – granular sponge, the metal as it leaves refining.
- Packaging – sealed, carrying its assay. Leave it intact.
- Premium – lower per ounce than bars, higher than our 10 oz unit.
Five Ounces in One Unit, or Five Separate Ounces?
This is the real decision at this level, and it is a trade between cost and divisibility.
A single 5 oz unit carries a lower premium per ounce than five 1 oz rhodium sponge units bought separately, because the seal, the assay and the handling are paid for once instead of five times. What you give up is the ability to exit in pieces. You cannot sell two ounces out of a sealed five ounce unit — it goes as one lot, or the seal comes off, and an opened unit is materially harder to place.
Buy the single unit if you are building a position you expect to hold and exit in one go. Buy separate ounces if you would rather be able to take part of it off the table later, and accept paying a little more per ounce for that flexibility. Going the other way, the 10 oz rhodium sponge lowers the premium again if divisibility is not a concern.
Sponge or Bar?
Five ounces of sponge and a 5 oz rhodium bar contain identical .999 metal. Sponge costs less because nobody has melted, cast, stamped or assayed it — you are buying metal rather than metal plus fabrication. The trade-off comes at resale: sponge often has to be melted and assayed before a buyer will take it, and that cost falls on the seller. A stamped bar carries its own proof.
Sponge if you intend to hold and want the most rhodium per dollar. A bar if you expect to sell and want the cleanest exit.
Sizing a Rhodium Position
Rhodium is not a metal to size like gold. The market is small, supply comes almost entirely as a by-product of South African platinum and palladium mining, and most of the world’s output disappears into catalytic converters and never comes back. That leaves prices free to move violently in both directions — rhodium has run to nearly $30,000 an ounce inside the last decade and fallen back hard afterwards.
Five ounces is a meaningful holding. Size it as the volatile, thinly traded, hard-to-value part of a portfolio, because that is what it is, and it should not be the part you may need to liquidate quickly.

Before You Buy
Rhodium is not IRA-eligible in any form — the IRS approves only gold, silver, platinum and palladium for precious metals IRAs. Spreads on rhodium are wider than gold or silver because the market is thin. And keep the unit sealed: the packaging carries the assay, and breaking it costs you money at sale.
Frequently Asked Questions
How much rhodium is in a 5 oz sponge unit?
Five troy ounces, 155.52 grams, at .999 fineness.
What is rhodium sponge?
Rhodium in its raw, finely divided form, as it comes off the refining line before being cast into a bar. Same metal, no fabrication.
Is one 5 oz unit cheaper than five 1 oz units?
Per ounce, yes. The seal, assay and handling are paid once rather than five times. You lose the ability to sell part of the holding.
Can I open the packaging to inspect it?
Better not to. The seal carries the assay, and an opened unit usually has to be melted and assayed again before another buyer will take it.
Can I hold rhodium sponge in an IRA?
No. The IRS approves only gold, silver, platinum and palladium.
How do I sell 5 oz of rhodium later?
We buy rhodium back directly through Sell to Us. Expect a wider spread than gold or silver — the rhodium market is small and moves in larger steps.
