Andalusite polished specimen

Andalusite is a highly fascinating and underrated gemstone celebrated for its incredible pleochroism, which is a optical trick where a single stone flashes entirely different colours depending on the angle you look at it. Often called "The Traffic Light Stone" or "Poor Man's Alexandrite," a single glance at a faceted andalusite can reveal a stunning blend of earthy olive greens, warm sunset browns, yellows, and deep brick reds all at the exact same time.
