This is an excellent combination piece with superbly intergrown sulfides,- Galena an Sphalerite. The Spahlerite is excellent developed, sharp edged and highly lustrous. It is perfectly tetrahedral shaped with excellent trunctations. The major Galena crystal is superbly formed as well and features an exquisite quadrangular pattern on its surfaces. A hopper growth on two edges additionally emphasizes the aesthetics. A super piece with great dramatics, way better in kind, from the heydays of this great mining area.
