An amazing, iridescent, peacock-blue with magenta highlights galena octahedron is perched on silicified limestone matrix on this fine specimen from the less well-known West Fork Mine of Missouri's Viburnum Trend. The sharp crystal is 2.3 x 2.2 cm, pristine and looks just like a very colorful Mayan pyramid. This is a very rare habit of coloration for galena. Outstanding material from this uncommon locality. Ex. Wes Parker Collection.
