There are several hexagonal tabular platelets of Apatite on this Brazilian specimen. They all have a moderate blue color, vitreous luster, and are transparent and very clear, approaching gem-quality! They range in size from a few millimeters to about 0.5"(1.3 cm) in diameter, and are no thicker than 3 mm. All are protruding from the host rock and intergrown, so that no complete and individual crystals are visible. They rest on a base of albite along with a substantial amount of muscovite and several quartz crystals- they are intergrown with a few. Many of the crystals are damaged or broken, but there are several that are intact and very beautiful.
