Perfect symmetry of gems
It is difficult to describe in words what it is that makes up the beauty of the crystalline mineral. Apart from the complexity and variety of crystal shapes, which often display near perfect symmetry, the most arresting attributes are probably the great range of colour coupled with the lustre and sheen produced by the reflection of light from the mineral’s surface. The present volume was conceived by the late Dr Ernst Peterson, who wanted to bring before his readers something of the beauty and variety of the mineral kingdom. In Arnold E. Fanck he found a photographer whose genius and infinite care with the camera did full justice to the selecte samples.
