Tounkite; Malobystrinskoye, Baikal, Russia; MM; unique piece
Tounkite from Malobystrinskoye, Baikal, Russia. Micromount as unique piece for mineral collectors.
This single micromount specimen features the rare borate mineral Tounkite from Malobystrinskoye near Lake Baikal, Russia – a highly unusual mineral species reported from only a handful of localities worldwide. It is a prime addition for collectors focusing on rare borates or Russian mineral occurrences.
Tounkite typically forms very fine acicular crystals and belongs to the group of extremely rare minerals. The Malobystrinskoye deposit in the Baikal region is well-known for its complex geological setting and has yielded a number of unique mineral species. Its hydrothermal environment fosters the formation of boron-rich compounds such as Tounkite.
This micromount is ideal for systematic mineral collections and offers excellent conditions for close-up, microscopic observation. With its well-documented provenance and natural matrix context, the specimen serves both as a scientific reference and a collectible rarity.
A significant find for advanced collectors: rare, clearly sourced, scientifically valuable, and presented in micromount format – Tounkite from Russia is a seldom-seen highlight in any curated mineral collection.
