I really do hope that this particular specimen sells quickly, because it's already caused me a lot of trouble just to find out exactly what it is made of! First, there are at least 20 thin, broad, curved blades of yellow Ankerite, which have moderate damage and a good, pearly luster. They measure an average 1/4"(6 mm) in length and half of that in height, and are translucent. The Ankerites rest on a bed of surprisingly clear quartz crystals that also have moderate damage, a good sparkle, and good form. The quartz crystals also average about 1/4"(6 mm) and rest on a bed ofquartz and maybe calcite intermixed with mariposite. I searched and finally found the book that would tell me if it even existed, looked it up, and found that it is a chromic variety of phengite. I looked that up, and found that 'phengite' is a silica-rich variety of muscovite! Needless to say, it is green. Somebody, please buy this and put it out of my misery!
