Perched aesthetically, high on matrix, is an equant, lustrous and translucent, colorless crystal of adularia, measuring 3 cm on an edge or 4 cm tall. It is sharply twinned. Adularia is a variety of orthoclase, and this classic, glassy crystal perched up on matrix is a superb example from the Swiss Alps.
