All of the crystals on this specimen form spinel-law twins. And looking closely at the crystals you will see all the incredible patterns on the faces probaly formed by stepped growth. The specimen sparkles nicely as you hold and rotate it. Very nice specimen, which is not your ordinary Galena specimen.
