Trade rocks, not cash.
Every collector has duplicates in a drawer and a want list in their head. RockSwap matches them up so you can swap specimen for specimen with collectors who have what you’re missing.

Your drawer
Their drawer
Common and Uncommon are only rough guides to how often a mineral turns up, not prices. Two specimens of the same mineral can differ enormously in worth depending on size, crystal quality, locality and damage. On RockSwap, the two collectors decide what is fair.
How a swap works
Catalog your duplicates
Photos, size, locality and condition grade. The more detail, the better the offers.
Build a want list
Name the minerals, fossils or localities you’re hunting for.
Propose a trade
One-for-one, two-for-one, or add a small piece to even it out. Counter until it feels fair.
Ship or meet up
Exchange tracking numbers, or hand off at a gem and mineral show. Then rate the trade.
What a trade board looks like
Trade in good faith
Sharp crystals, no visible damage. Display quality.
Minor dings or chips you’d only notice up close.
Noticeable damage, but still a good study specimen.
Always label where it came from. A specimen without a locality is just a rock.
