A 2.8 cm vug is richly lined with sparkly, triangular, dark olive-green olivenite crystals on this fine, old-time specimen from the Tsumeb Mine. Olivenite actually richly infuses the matrix and malachite and azurite are a nice accent. The matrix also has massive germanite ore. An interesting and weighty combination piece. Classic material from the Mullane Collection and comes with an old Burminco label dated July, 1951, just after the mine reopened following World War II.
