As of August 28, 2007, there are 866 images on the Agate Page.

At Right: Blue Chalcedony, commonly called Blue Agate, was named Nebraska's state gemstone by legislative action in 1967.

Introduction

Approximately 40% of the images are from the United States (30 US states are represented in the database). The remaining 60% are from 36 foreign countries and Antarctica, spanning all seven continents.  Many of the agates include descriptive text. As time allows, text will be added for the remaining agates.  Many of our images have come from collectors all over the world.  If you are interested in contributing, please see instructions below.

Using The Agate Page Data Base

Note that there are several search options:

1. Country - List of all countries.
2. Contributor - Several agate collectors from around the world have found our Agates Page and subsequently sent us images, many with descriptions. In order to recognize and thank them, we have added this list by which to search on their names.
3. United States, Australia, Canada, and Mexico.  Because of the large numbers of agates from these four countries, we have offered the option of listing agates from these countries' major political subdivisions (state, province or territory). Or, you can list all the agates from the country by using the "Country" list.

Some records contain "na" (not available or not applicable).  This information has either not yet been entered, or is not applicable (e.g. the "State" field for countries that have not been listed by political subdivisions). An "na" in the "Location" field is used when a more precise location beyond major political subdivision cannot be determined. Normally, the "Location" is a nearby town or physical feature (river, mountain, quarry, etc.). Many images were either anonymously donated or belong to Roger Pabian. These images are also notated with an "na".

To Contribute

Many of the images used in the Agate Page have been generously donated by collectors from all over the world. If you have images you would like considered for this web site, contact Professor Roger K. Pabian (see below). Agate images from countries and/or political subdivisions (states, provinces, territories) not listed are especially encouraged.

Reference Maps

For a quick reference of the countries that we have images from, click on one of the major land masses (Africa, Asia, Central America, Europe, South America) indicated on the world map. Four countries (Australia, Canada, Mexico, United States) have large numbers of images; therefore, they have their own maps with their respective subdivisions (states, provinces or territories) highlighted.
