Leopard rock is a hard and rare variety of serpentine stone. This particular variety is really only found in a few small mines in Nyanga, Eastern Zimbabwe. The more strongly yellow ones are likely from Shamva, north of Harare. Hence, these are quite rare stones. These kinds of mines are really just local villagers digging by hand in small areas for income, without much, if any machinery, and hence are not really environmentally taxing. Due to their uniform structure and hard nature, they are often used in the local sculpture works.
