Puzzle #72 was abellaite.
Abellaite is a hydrous carbonate mineral discovered in the abandoned Eureka uranium mine in the village of La Torre de Capdella (Lleida province), Catalonia, Spain. The ideal chemical formula of abellaite is NaPb2(CO3)2(OH). It is named in honor of Joan Abella i Creus, a Catalan gemmologist who has long studied minerals from the Eureka mine and first found abellaite in the mine.
