Osmium, Big high purity arc melted bead 5,03 grams
Diameter around 9mm
This practically unavailable noble metal is almost unknown in solid form since only a few producers accept the high risk of damaging their equipment and compromise their health by melting this metal which results in a higher price. Only the result is safe: A solid bead with shiny surface and slighty sky-blue tinge.
A must have for every elements collection!
