Quartz (Closed Japan Twin)
Miniature, 5.0 x 3.1 x 2.8 cm
Washington Camp, Santa Cruz Co., Arizona, USA

A superb twinned quartz on matrix from this classic locality showing highly unusual sharpness of form, and the more rare of the Japan law twinning styles which is seldom seen. Very aesthetic, and a superb example crystallographically as well.
