A classic, very showy combination specimen from the famous mines at Concepcion del Oro, Zacatecas, Mexico. Interesting, two-toned, velvet malachite botryoids are richly and aesthetically scattered on the 3-dimensional matrix with lustrous, colorless calcite crystals and an overgrowth of sparkly, drusy quartz. One malachite cluster looks just like barbells. Older material from the Mullane Collection.
