This exotic metal is one of the fourteen other metals in the so-called Rare Earths group, none of which play any major role in industry outside of very specialized uses. Each one may have found its niche whether in lasers or as dopants with other elements to impart a desirable property. Holmium's claim to fame is as the Numero Uno among supermagnets beating out fellow Rare Earther neodymium for the title but much less popular due to it needing external activators.
Anyway, this small acrylic cube, which is meant to fit our medium periodic table case display as sold on our website, contains a 99.95% pure holmium metal. The gel-filled cube makes for an attractive addition to your collection of elements. As you hold it in your hand watch as the sample slowly tumbles into new positions!
