The title of rarest metal is a matter of controversy but iridium is always one of the top contenders. In addition to being super rare, iridium's extraordinary noble character finds uses in chemistry where an equally extraordinary resistance to corrosion is called for. And extraordinary also happens to be a good adjective to describe the fetching price of this handsome metal. 

For this tier we reserve the very best iridium specimens. Each weighs around ten grams, is 99.95% pure and selected to wow anyone who’s heard of this metal. It has been perfectly set in this block of Lucite acrylic measuring 50mm per side. It is in every sense of the word a one of a kind trophy whose equal you'd be hard pressed to find anywhere else!
