Minerals: Greisen (Complex intergrowth of Massive Topaz, Quartz, and Zinnwaldite Mica). This piece was sourced from the legendary Einstein Silver Mine in the Missouri Ozarks. The mirror-like finish acts as a perfect window, beautifully exposing the dark, localized flecks of rare Zinnwaldite mica suspended deep within the dense, glassy intergrowth of massive topaz and quartz.
