Osmium

Osmium is the eighth and last precious metal. The crystalline, non-hazardous form of osmium, also referred to as “osmium” on this website, is available for purchase only since 2014. 

Due to its extraordinary rarity and high value density, crystalline osmium is used exclusively in the manufacture of premium jewellery and timepieces, and as a store of value.

Osmium is not only one of the rarest precious metals but also one of the rarest chemical elements on our planet. Osmium is mined together with platinum ore. To obtain just 30 grams of osmium, about 10,000 tons of platinum ore are required.


The extraction of the osmium from the platinum ore and the crystallisation of the osmium are both very complex and cost intensive processes. The current global production rate of crystalline osmium is just 120 kg per annum. In time, when the mining of platinum ore declines, the production rate for osmium will decline accordingly and osmium will become even more rare.

Opportunities with Osmium

Osmium is seen in the market both as an investment and jewelry metal. Due to the special properties of osmium, there exist many other potential applications; however, osmium is too rare and too expensive for any of these applications.

Investors with a long-term perspective are therefore predominantly betting that, due to its rarity, osmium will become increasingly difficult to acquire for jewellers. In the future, private and institutional investors will supply the jewelry market with crystalline osmium in bars or disk form or in the form of osmium diamonds and osmium stars.

Osmium jewellery

The use of osmium in the manufacture of exclusive jewellery, timepieces and other luxury goods is constantly rising. 

To date, two-dimensional osmium pieces, i.e. osmium bars cut into specific shapes, have been predominantly combined with other (precious) metals such as gold, silver, platinum and titanium. It has now more recently become possible to crystallise osmium onto three-dimensional substrates of almost any shape, opening up a virtually unlimited spectrum of options for jewellery designers, manufacturers and retailers! 

However osmium is used in the manufacture of jewellery and other luxury goods, its rarity, unique surface crystal structure and distinct bluish-silvery to bluish-whitish lustre impart a sense of exclusiveness, timelessness and sophisticated understatement to the final product.
