These are some of the better available crystals of Libethenite, a rare copper phosphate. They are miniscule, not reaching more than 1/16 inch in diameter, and are dark green. The well-defined pseudotetragonal crystals have clean surfaces and edges, with a sparkly, vitreous luster. Libethenite is a mineral of great rarity- I doubt that very many collections can boast a specimen of it.
