Magnetite 2,500 foot Level of the Zinc Corporation of America Mine, Balmat, St. Lawrence, County, New York. Ex. Chuck Bowman, Z.C.A. miner and collector of specimen. Rare, well documented, and important material that is unique to the mineralogical world. It also ranks among the best known for the species. This example shows both of the important forms (cubes with tetrahexahedral modifications to faces) in a couple large, beautifully formed, damage-free crystals. The luster is lower because the tetrahexahedral faces dominate (and they always tend to have lower lusters). 4 x 3.3 x 2.2 cm. Base and minor edge contacts. Everything else is well crystallized and free of damage. $200
