This is a museum specimen both in size and quality. Translucent octahedral crystals of purple ("raspberry") fluorite completely cover the top of this specimen from Mina Navidad, Abasolo, Durango, Mexico Excellent condition. Measures 12.5 x 9.5 x 4.5 inches (31.5 x 24 x 11.5 cm). Weighs 18 pounds. Would be best if it could be picked up at my shop to avoid shipping costs, but could probably ship in large flat rate box.
