Basics

What makes osmium special

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).

  • Extremely rare. Only a tiny amount of recoverable osmium exists on the entire planet.
  • Highest density. No element is denser — a small piece weighs surprisingly much.
  • Forgery-proof. Unique crystal surface, scannable and certified via OIC.
  • Tangible asset. Scarcity-based and independent of classic stock exchanges.

Why osmium

Four reasons people look at osmium

Unrivalled rarity

Rarer than gold, platinum or rhodium. Scarcity is the strongest value driver of any tangible asset.

Densest of all metals

22.59 g/cm³ — no element is denser. This is exactly what the famous osmium cube shows off.

Forgery-proof

The crystal structure is a physical fingerprint — scannable via OIC and stored in the World Database.

Price development

Since the first issue in 2017 the osmium price has risen strongly — scarcity-driven.
