## 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.

## 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](https://www.osmium-group.com/en/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.

## Osmium vs. gold — the key differences

| 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 |

## Rare. Forgery-proof. For eternity.

Every crystalline piece carries a physical fingerprint — non-reproducible and assigned to you via the OIC.
