Small edged bars are osmium bars (“stars”) with concave sides and a maximum diameter of approx. 3 mm. The thickness is approx. 1 mm. The underside is a plane surface. Osmium stars are the geometric counterform of osmium diamonds, resulting in minimum material loss during the cutting process. Accordingly, they have a high osmium weight per unit price ratio.
Individual osmium stars are obtained by cutting / breaking the thin bridges of star rows. They can be worked into jewelry and harmonise well in combination with other precious metals. Due to their size and favorable geometry, jewelers can handle osmium stars with ease.
