Buying guide
Buy osmium — safe, certified & forgery-proof
Osmium is the world’s rarest precious metal — and buying it follows clear rules. Here’s what really matters with crystalline osmium, the OIC certificate and denominations, so your entry is secure.

OIC certificate
Every genuine piece has an Osmium Identification Code (OIC) stored in the World Database — your proof of authenticity and ownership.
Verified dealer
Buy through the network of Osmium Institutes or certified partners. Avoid offers without verifiable certification.
Small entry possible
Small denominations such as discs or stars make entry easy — you don’t have to buy a whole gram at once.
