This manganese mine in Brazil has a long history... for manganese ore and the occasional manganite crystal from 100 years ago! Stunning, cherry red rhodonite crystals came out once before, and again recently... nearly ten years apart! Buy them while you can. This superb gem thumbnail sized crystal came to us in a lot through a friend who found them for sale as cutting rough at one of the gem shows in Tucson 2024... scary thought, that!
