Neighborite xls, Bohnstedtite xls; Kovdor, Kola, Russia; MM; unique piece
Neighborite and Bohnstedtite crystals from Kovdor, Kola, Russia. Micromount as unique piece for mineral collectors.
This rare combination of Neighborite and Bonshtedtite comes from the renowned alkaline complex of Kovdor on the Kola Peninsula in Russia – a globally significant locality for rare minerals. The offered miniature specimen features both minerals in close association, making it an excellent addition to systematic collections focused on rare borates and fluorides.
Neighborite is a rare fluoride mineral with the chemical formula NaMgF₃. It typically forms as small, colorless to pale yellow crystals under highly specialized geochemical conditions in pegmatitic zones of carbonatite complexes. Bonshtedtite, on the other hand, is a sodium iron borate usually found as whitish-gray microcrystalline aggregates. Both minerals are associated with the highly evolved magmatic processes characteristic of Kovdor.
The Kovdor locality is one of the most important sources of rare mineral species worldwide. Many type-locality minerals were first described from this area, which continues to be of high scientific interest within the field of mineralogy.
This micromount specimen is ideal for collectors specializing in borates, fluorides, or minerals from alkaline igneous complexes. Presenting two uncommon species in one aesthetic composition, it offers both visual appeal and geological significance – a valuable specimen from one of Russia's most productive and scientifically important mineral localities.
