Collection: Cubic Magnetite

This collection features hard-to-acquire, world renown Cubic Magnetite specimens from the famous ZCA #4 mine in Balmat New York. Considered among the finest examples of magnetite morphology, cubic magnetite specimens from New York are prized for their striking geometry, jet-black luster, and rarity among North American minerals. While magnetite typically forms in octahedral shapes, the Balmat specimens often display dominant cube faces, sometimes with subtle tetrahexahedral modifications, making them exceptionally unique. The cubic magnetite specimens from were recovered in 1991–1992 during sphalerite mining in an altered zone containing halite-filled veins. These specimens represent a ‘flat’ acquired in 2015 from a miner in upstate New York with a connection to the ZCA #4 mine.
