This small thumbnail specimen consists of two visible and complete Pyrochlore crystals that are partly embedded in a black-and-white granular host rock. The crystals have dimensions of 2 x 2 x 2 mm and 0.3 x 0.2 x 0.2" (8 x 5 x 5 mm), and are in excellent condition, showing no visible damage. Their octahedral form is very good, as they have well-defined edges and clean faces. Their color is black, their luster is submetallic, and they are both completely opaque. The surrounding host rock seems to be made up of granular quartz and well-formed pseudohexagonal "books" of biotite that were compacted into a rock of sorts. The piece is attached to an acrylic base with hot glue.
