Spinel on Calcite
Without question, this vivid red, gemmy, octahedron of spinel on white calcite, is a world class competition thumbnail. Most Mogok spinels are simply loose singles, off matrix. This one, carefully excavated from a miniature at Bill Larson's lab by Irv, is unrepaired and remains on matrix due to the careful prep work. You almost never see this quality of crystal , aside from the additional aesthetics of it being on matrix! The well formed , complete crystal measures .8 cm across. It is truly a thing of beauty.
