Accessible only by boat, the Marble Caves in Chile are isolated, sculpted caves. They lie in the General Carrera Lake in the heart of the Patagonia region. Comprised of swirling black and white columns reflecting the azure and turquoise waters of the lake, the colors change throughout the seasons. This ocean jasper, with its swirls like a magical colorful cave entrance, measures a height of 4.5" and weighs 2lbs.
