Unrivalled rarity
Rarer than gold, platinum or rhodium. Scarcity is the strongest value driver of any tangible asset.
The world’s rarest precious metal
Osmium is the rarest stable element on Earth and the densest of all metals. In crystalline form it’s a forgery-proof precious metal. Here’s everything on the price, the famous osmium cube and where to buy safely.
Basics
Osmium belongs to the six platinum metals and is the rarest non-radioactive element in the Earth’s crust. Only in the last 10–15 years has it become possible to turn it into a stable, safe-to-handle crystalline form with an unmistakable silvery-blue shimmer.
Every crystalline piece carries a microscopic surface that cannot be reproduced — like a fingerprint. That makes osmium forgery-proof and uniquely traceable via the Osmium Identification Code (OIC).

Why osmium
Rarer than gold, platinum or rhodium. Scarcity is the strongest value driver of any tangible asset.
22.59 g/cm³ — no element is denser. This is exactly what the famous osmium cube shows off.
The crystal structure is a physical fingerprint — scannable via OIC and stored in the World Database.
Since the first issue in 2017 the osmium price has risen strongly — scarcity-driven.
Comparison
| Criterion | Osmium | Gold |
|---|---|---|
| Rarity | Rarest stable element | Rare |
| Forgery protection | Crystal fingerprint (OIC) | Hallmarks / testing |
| Density | 22.59 g/cm³ — highest | 19.3 g/cm³ |
| Look | blue-silver crystal | classic gold |
Unique in the world
Every crystalline piece carries a physical fingerprint — non-reproducible and assigned to you via the OIC.
