Dundasite

This specimen features a radiating spherical aggregates of acicular white dundasite crystals, a truly rare specimen. The piece is visually striking up close and offers an excellent opportunity for detailed examination of numerous micros such as azurite, malachite, goethite, et al. when viewed with a loupe or under a microscope. The specimen originates from a significant polymetallic deposit rich in zinc, copper, and lead ores, which weathered into secondary minerals such as azurite, malachite, and cerussite. Unfortunately, little material remains for collectors due to the mine's closure in 1982. Despite this, the locality is noteworthy, with nearly 100 species reported, making it a highly sought-after source for rare minerals.
