Beautiful cluster of superb Pyrite crystals. The brassy Pyrites are sharp cubes with some specific for the mine elongated habit. They are strongly lustrous and light reflective with pleasing yellow color. The faces have nice striations and some crystals show penetration twinned. Minor Sphalerite is seen too. Complete all over with small contact point. In very good condition – some small nicks and contact.

Splendid piece!
