Mineral Spot: Smithsonite...

Smithsonite is a zinc carbonate mineral that occurs in the oxidised zone of lead-zinc ore deposits.

Good crystals of smithsonite are not that common and are often white or greyish in colour. It sometimes occurs as pale coloured crystals in various hues due to impurities.

This specimen is green due to copper and comes from Broken Hill in New South Wales. This particular specimen will be included in one of my auctions starting this coming Sunday...
