This fine miniature specimen is from the premier US locality for ludlamite, the Blackbird Mine of Idaho. The matrix plate is richly covered with gemmy, intergrown, olive-green crystals to 8 mm. The crystals have superb euhedral form, are translucent and sharp. The largest crystal is attractively perched at the top of the piece. Ludlamite from this locale is world-known as among the best crystals of the species for those characteristics. Most of these came out in the 1960s and the mine is long since closed. Ex.
