This rhodochrosite specimen, called “The Porcupine,” came from the Kalahari Manganese Field in the Northern Cape province of South Africa. It’s expected to fetch between $35,000 and $50,000 in Bonhams May 20 auction.

The top lot of the sale is a collection of 27 rhodochrosites, commonly known as “red gold,” ranging in hue from a light rosy color to the rare cherry-red shade. The group is expected to fetch between $200,000 and $250,000.
