This odd specimen does not look at all like Quartz because it is a pseudomorph of aegirine- this simply means that the aegirine was replaced by Quartz, which reatined the shape of the earlier mineral. Thus, though these intersecting crystals are made out of Quartz, they appear to have good monoclinic prismatic form. They are in very good condition, showing no fresh damage, and possess a dull, pale gray coloration and a matte luster, though scores of tiny crystals embedded in their surfaces give the crystals a subtle sparkle. What appear to be a few tiny smoky quartz crystals are embedded at the juncture of the intersecting pseudomorphs, but there is no host rock present.
