The best jewelry grades of Rhodocrosite come from two silver mines in Argentina. This material was mined in 1972. The Indigenous Peoples of South, Central, and North America considered Rhodocrosite to be a Holy Stone. It was traded up and down and along the river systems throughout the Americas. It was known as “the Rose of the Incas”. There are a number of types and grades of Rhodocrosite. Ortiz is the rich colored fine or gem grade of this material. It is transparent or translucent and is an incredibly rare occurrence. Stalagmite and Stalactite is another rare variety of Rhodocrosite. It is known for its Bull’s-eye patterns. There are also floral, striped, and geometric patterns that occur in this material.
