Ten troy ounces of .999 fine rhodium, sealed as it left the refinery. Our largest sponge unit and the lowest premium per ounce we offer, for buyers taking a serious position in the rarest of the precious metals. Priced live against the market, shipped fully insured.
Buy 10 oz rhodium sponge in a single sealed unit — ten troy ounces of .999 fine rhodium at the lowest premium per ounce we carry. This is the largest rhodium sponge we stock, and it is aimed squarely at buyers who want weight rather than variety. If you have already held rhodium and want to build the position properly, this is the efficient way to do it.
What You’re Buying
- Weight – 10 troy oz (311.03 g) of rhodium.
- Purity – .999 fine.
- Form – granular sponge, the metal as it leaves refining.
- Packaging – sealed. The seal carries the assay; leave it intact.
- Premium – the lowest per ounce of any rhodium we stock.
Why Buy Sponge at 10 oz
Premium per ounce falls as unit size rises, and it falls hardest on sponge because there is no fabrication cost built in to begin with. A minted bar has been melted, cast, stamped, serialised and assayed, and every one of those steps is priced into what you pay. Sponge skips all of it. At ten ounces, the saving against buying the same weight in rhodium bars is the largest it gets across our range.
The trade-off is verification. A stamped bar carries its own proof; sponge relies on the sealed packaging and its assay documentation. That matters more the larger the position, which is why the seal on a 10 oz unit is not something to break out of curiosity.
Holding a Position This Size
Ten ounces of rhodium is a substantial single holding, and it is worth thinking about storage before it arrives rather than after. Keep the unit sealed and somewhere cool and dry — rhodium does not tarnish or corrode, so the enemy is handling and broken seals, not the atmosphere. For a holding at this level most owners use a home safe, a bank deposit box, or an insured vault service, and check that their contents insurance actually covers precious metals rather than assuming it does.
Resale is the other thing to plan. Rhodium trades in a thin market, and a ten ounce unit finds fewer buyers than a one ounce one simply because of the ticket size. We buy rhodium back directly, which for most holders is the cleanest exit.
Sponge, Bars and Coins
- Sponge – most rhodium per dollar. Best when you intend to hold.
- Bars – serial numbered and assayed, easiest for a buyer to verify.
- Coins – the rarest form, with collector premium on top of metal.
Smaller entry points are available: the 1 oz rhodium sponge and the 5 oz rhodium sponge carry the same purity in lighter units.
Where Rhodium Comes From
Rhodium is a platinum group metal recovered as a by-product of platinum and palladium mining, overwhelmingly in South Africa. World production each year is a small fraction of gold’s, and the great majority of it goes into catalytic converters and never returns to the investment market. That combination — tiny supply, industrial demand that consumes it — is what makes rhodium both scarce and violently volatile.

Before You Buy
Rhodium is not IRA-eligible in any form: the IRS approves only gold, silver, platinum and palladium. And rhodium’s market is small enough that spreads are wide and price swings are sharp in both directions. At ten ounces those characteristics apply to a large sum, so buy the size that fits the position you actually want.
Frequently Asked Questions
How much rhodium is in a 10 oz sponge unit?
Ten troy ounces, 311.03 grams, at .999 fineness.
What is rhodium sponge?
Rhodium in its raw, finely divided form, exactly as it comes off the refining line before anyone casts it into a bar. Same metal, no fabrication.
Why is sponge cheaper per ounce than a bar?
Because nobody has melted, cast, stamped, serialised or assayed it. You are paying for metal rather than metal plus fabrication.
Should I open the packaging?
No. The seal carries the assay, and an opened unit is materially harder to sell on.
Can I hold rhodium sponge in an IRA?
No. The IRS approves only gold, silver, platinum and palladium for precious metals IRAs.
How do I sell 10 oz of rhodium later?
We buy rhodium back directly through our Sell to Us page. Expect a wider spread than gold or silver — the rhodium market is thin, and larger units find fewer buyers.
