Tellurium (Te) 1 kilogram bar

Tellurium bar - one kilogram - .9997 bullion       First identified as an unknown metal in gold ore (calaverite) near the present day city of Sibiu, Romania, tellurium's discovery in 1782 would eventually be credited to Franz-Joseph Muller von Reichenstein who spent three years on laboratory work to characterize this metal.

This new element would later be named tellurium by Martin Heinrich Klaproth in 1798. Tellurium is extremely rare in the Earth's crust (see below link to our favorite chart detailing where our metals fall in terms of their relative rarity), about as rare as platinum.
