Gemologist Notes:
This red andesine feldspar has undergone copper diffusion treatment, a process responsible for its saturated red coloration. Early claims of untreated origin from various regions—including the Congo, Tibet, Mongolia, and China—were later challenged by independent gemological research, which demonstrated the material to be treated common feldspar. This gemstone is offered with full disclosure and priced accordingly.
