Rock forming minerals such as feldspars are rarely collector-quality and even rarer to find them as gemmy crystals. This specimen incorporates several complex, intergrown crystals of gemmy white adularia to 5.8cm. It is of very rare quality and for its luster and brightness is remarkable! The piece is contacted on one side and at a single point on another crystal. This represents another outstanding classic, having likely come out of the ground over 100 years ago. Several previous collections labels are included.
