A beautiful, classic and old-time specimen from the famous Wheal Gorland of Cornwall. The two large pockets are lined with very sparkly, dark forest-green, botryoidal Olivenite microcrystals in the quartz-rich matrix. Primary production at Wheal Gorland was over by 1851. Seldom are Wheal Gorland Olivenites of this richness and quality available and only from recycled, older collections (note old museum label), and this is a large and showy museum-sized specimen, indeed.
