Many tiny (sub mm), dark grey to black metallic grains of Magnetoplumbite are embedded within larger aggregated 'books' of Phlogopite mica that form the distinctive matrix of this miniature specimen. This association is typical of Långban, in Sweden, which is the Type Locality for the extremely rare species Magnetoplumbite. It is from the superb systematic collection assembled by the brothers Martin and Michael Günther (1951-2007 & 1956-2021).
