Ilvaite (doubly-terminated) on Quartz (ex Dr. Stephen Smale Collection)

Item Description

Here we have a beautiful combination specimen features a showy Ilvaite aesthetically perched across the prismatic stepped Quartz crystals. The ilvaite is nearly complete-all-around, and is actually doubly-terminated, though part of the termination on one end is contacted. The ilvaite terminations are sharp and tapering, and the crystal group couldn't be set more beautifully on the Quartz. This association produces a highly desirable (and rarely seen) color contrast, and this material is already a contemporary classic and a staple from this prolific mine.
