Spurrite is one of those mineral species which never really presents as good crystals, rather more of a type of rock. That said, this calcium silicate carbonate is rare and specimens from either of the Co-Type Localities are extremely hard to come by. This miniature specimen comes from one of those - Terneras mine, Velardeña, in Durango, Mexico - and was in the superb systematic collection assembled by the brothers Martin and Michael Günther (1951-2007 & 1956-2021). Much of this piece is Spurrite, presenting as colourless to white crystalline masses similar to marble in appearance.
