This gemmy Adularia is outstanding for form, clarity, and association. This slender, tabular crystal has a front face with superb luster, decorated by gentle hillock features that look like reverse Heliodor etchings. It is gemmy through and through, with a "Faden"-like growth roughly parallel to the C-axis. The clear crystal is tinted a soft green by the included Byssolite needles. "Faden" is the German word for string, and the term is most often applied to Epidote or Quartz specimens where the crystals have grown around and over a thin string-like mineral (typically some kind of Amphibole), creating a distinctive growth line through the specimen. For a final touch, there are some beautiful bluish-green needles of "Byssolite" completely included, and exposed, in this fine small cabinet specimen. Unusual!
