AGATES (part III)
By: Johann Zenz
From Austrian collector Johann Zenz, this third installment of the gorgeous agate trilogy is the first detailed publication ever on worldwide jasper locations. It includes wonderful jaspers from the famous Hans Gamma Collection, with world-class jaspers from Oregon, Arizona, Nevada, California, and many other US locations. So closely related to agates, this feature on jaspers also includes localities from Indonesia, South Africa, Egypt, Morocco, Madagascar, Australia, and Russia.
An updated chapter on collectors includes another 60 top agate, jasper, and petrified wood collectors from all over the world. Other agate updates includes new and old worldwide agate locations such as Agate Creek, Australia, rare agates from Germany, and the best agates from Ploczki, Poland.
A separate chapter comes from leading expert in agate genesis Prof. Dr. Jens Götze. It presents research regarding the geological occurrences, mineralogy and microstructure of agates and their formation, and addresses topics like uncommon features, trace elements, inclusions, luminescence, and color.
Full of interesting text and amazing color images of agates, jaspers, landscapes, and maps, this completes the set of the most influential and comprehensive books on agates in existence.
