This is the upscale, slightly purer version of dysprosium for those who want to own a stylish piece meant as a collectible (or simply must have the purest grade available).

Dysprosium is a rare earth metal that comes from China - the only country currently mining and refining it in commercial quantities. And that commerce trades at a fever pitch as electronics and specialty magnets soak up every pound of this rare metal.

Getting back to the needs of the collector, while the branching is evident even in sub-gram amounts the textures really come to life in pieces weighing ten grams or more. These chunks in the photo each weigh about 50 grams each and are the size of a pack of cigarettes.
