Agates: Treasures of the Earth

A well-illustrated reference for agates including an introduction to their geology and formation, a comprehensive identification guide and listings for where they can be found around the world.

"Superbly done... should be high on everyone's 'must have' list."-- Rock and Gem

This book has been very well received as the first popular guide to these brilliantly banded and highly prized gemstones.

The agate is one of the world's most strikingly beautiful semiprecious gems. Collectors worldwide are drawn to the stone's infinite variety of coloration and banding. While these stones are readily available, the rare and higher-quality ones are quite valuable and aggressively collected.

Agates is a comprehensive reference written by one of North America's leading experts in cooperation with the Natural History Museum of London. The book features an easy-to-use identification guide and a worldwide listing of where agates are found. More than 200 color photographs of superb agate specimens were selected from the extensive collection of the Natural History Museum of London and from the private collection of author Roger Pabian.


Roger Pabian is a research geologist, invertebrate paleontologist and highly respected specialist in agates. He lives in Lincoln, Nebraska.

Brian Jackson is head of mineralogy at the National Museums Scotland and professor emeritus at the University of Nebraska-Lincoln.

Peter Tandy is curator of mineralogy at the Natural History Museum in London, England.

John Cromartie is a collector of Scottish agates.



Agates are probably the most common gemstones on Earth. They have been used to create ornaments for around 7000 years, and have been recorded on every continent and in several different geological environments. Since the mid-1900s, agate collecting has become very popular in Europe, North America and the Middle East. There are thousands of agate-producing areas on Earth, and in the following pages, you will become acquainted with a small, but representative sample of these fascinating gems.

The formation of agates is of scientific interest to a range of scientists, from geologists investigating their geological significance to chemists studying the formation of chalcedony within water pipes in geothermal areas. This book is intended to present the current state of knowledge of these gems. Thus, the goal is to acquaint the novice and remind the advanced collector of the rich geological and cultural significance of these most beautiful stones, and to take the reader on a tour of the geographical distribution of agates across the world.
