Fragment of transparent ice-like monograin of chiolite. When seeing on the specimen begin to understand, that name for chiolite(=snow-stone from Greek) was mixed up - this mineral much more similar to ice, than cryolite (=ice-stone from Greek). But on the type locality chiolite really is similar to dirty snow in March... Associating mineral is dessiminated green chlorite. Specimen size is 5x3x2 cm. Pavel M. Kartashov collection and photo.
