This sample of ultrapure dysprosium stands on its base as though it grew from unseen roots into a glorious, twisty metal tree straight out of a sci-fi movie. The dense mass of metal dendrites have formed according to the laws of physics as known to this and only this element. Any other might have a shape that is loosely similar but just not the same. And yet, each coil of dysprosium is also unique; an uncountable number of alike atoms coming out of melt and jostling to take their place in this edifice; twisting exactly this way and not a fraction of a degree in another. Then the reaction stops and the creation is made. Complete. As long as it stays protected in this glass dome it will continue to mesmerize with its otherworldly charm.

A gorgeous, ~150g chunk of 99.99% dysprosium in a format that will make every other element collector green with envy.
