A really fine small cabinet specimen of Bournonite from Baia Sprie in Romania. Crystals of metallic grey cogwheel habit Bournonite measuring to 9 mm are abundantly clustered and scattered over the Quartz matrix to excellent effect, associated with areas of minor light metallic yellow Pyrite. The Bournonite crystals really do look like gears or being pedantic, pinions. For all readers familiar with constructing models made with Meccano, these crystals bear a marked resemblance to the No. 25a pinion! Whatever, this is a rich specimen of Bournonite from the Baia Sprie mining area and comes with a Oliver Konczer Collection label (Germany).
