One thing in advance : THIS EXTRAORDINARY SPECIMEN IS MUCH BETTER IN PERSON!!! A superb cluster of intergrown cubed Galena crystals up to 3,7 cm. They are super sharp and excellent terminated without any damage on the display face. The metallic sheen is so high, that good pictures were almost impossible and consequently, the pictures cannot convey the 3-dimensionality and quality of the piece. So much better in kind.
