50 gram chunk of Yttrium metal. This sample has a unique shape: a quarter slice of a dome or bowl. That’s equal to 1/8th of a sphere, also known as an “octant.” This sample has dulled and slightly darkened over years of exposure to air.

Small pieces of Scandium , Yttrium , and Lutetium . In the past, it was debated whether these three elements are transition metals or rare-earth metals, but the consensus now is they're all rare-earth metals.
Four chemical elements were named after the town of Ytterby, Sweden, where many rare-earth elements were discovered from the ores mined there. In this photo is Yttrium (large chunk), Ytterbium (in ampoule), Terbium (brassy pieces), Erbium (silvery pieces). Also included are small pieces of dull, slightly oxidized Holmium , which takes the name of Stockholm, Sweden.
