“Large gray metallic galena crystals up to 20 mm across with transparent colorless quartz crystals up to 24 mm long. The galena crystals exhibit hoppered growth, skeletal crystals with rounded edges that make them look like they melted.
Note the many small cavities visible throughout the galena.
Size overall: 16x11x6.5 cm”
