Perfect, like from a textbook, K Feldspar var. Adularia crystal from Italy. Displays complete all over, razor sharp 21mm crystal. It is with very high luster, transparent, glassy and colorless. Some partial coating of green Chlorite is well visible. One very small Quartz crystal grows at the top. In very good condition – some small damages on the back side. On acrylic base.
Marvelous!
