The extremely rare calcium borate hydroxide hydrate species Olshanskyite is only known from three places on Earth. At the first of these - the Type Locality - at Titovskoe B deposit, Dogdo River Basin, Polar Yakutia, Sakha, Russia where it was discovered in the 1960s it is only known as layered masses of virtually structureless form. Then, in 1994, tiny but distinct crystals were encountered at Fuka mine in Okayama Prefecture, Japan. However, it was finds made at Shijiangshan mine in Inner Mongolia, China, after 2010, for which this species is really known to collectors. This larger miniature sized specimen from the superb systematic collection assembled by the brothers Martin and Michael Günther (1951-2007 & 1956-2021) shows this quality perfectly, with long bladed glassy colourless Olshanskyite crystals reaching to nearly 2 cm in length aggregated together in an extremely richly presented aggregate.
