Tiny, lustrous, lathes of primary malachite crystals are richly and attractively sprinkled in clusters on the hummocky matrix plate covered with starkly contrasting, sharp, limonite-stained quartz crystals on this classic, old-time specimen from the famous mines at Concepcion del Oro, Mexico. Excellent combination material from this locale. Ex Bideaux and Mullane Collections.
