Cochise College: Photo Index of Minerals

Most common minerals are identified visually by taking into account color, transparency, luster, crystal shape, cleavage, bruising, mineral habit, and mineral associations. This knowledge is acquired by observing many examples of how minerals may vary. This collection of mineral photos has been designed to assist in this learning process.


The online educational encyclopedia, Mineral Section.


Extensive website of information on all aspects of geology. Many detailed topographic maps, articles, pictures, news, satellite maps and much more! We met Hobart King (website owner) at the 2008 Tucson Gem and Mineral Show and had a lovely chat about mineral websites. Hi There, Hobart!


Welcome to the internet’s most exciting gemmology resource with pictures and everything else! We are in the process of adding to our content in the new-look website, so expect more and more gemmological information as the weeks go by.

YOU have a role to play! We invite you to submit gemmological information on rare gemstones. Information on stones like Painite, Poudretteite, serendibite, grandidierite, majorite, jeremejevite, taaffeite, musgravite, benitoite, etc would be most appreciated as we seek to expand on our substantial library of work. Your latest papers and articles are most welcome!

Alan Guisewite’s Mineral Collection

The uncredited images are mine – the remaining images are attributed to and copyrighted by their respective authors. Any errors in attribution are mine (and accidental) – if (when) you find any please get in touch with me, adg@cmu.edu, so I can correct them. Obtaining quality specimens through the Web and online auctions has made it possible for me to have a much better collection than I would have otherwise and I don’t want to slight anybody!

My images are essentially unretouched – I have occasionally increased the contrast or sharpness to clarify things. I don’t have a lot of control over the lighting – it’s warmer than I’d like, and the camera tends to oversaturate a little. So, my i mages tend to come out a little redder than they appear in person.

Pegmatites International

Pegmatites International is a site intended for those who have experienced the Wonderful World of “Pegmatology” (the study of pegmatites) and want to know more. It’s designed for the non-pegmatite specialist, the professional geologist and the beginning and graduate student. It will offer a good starting point for both general and advanced information and provide a greater insight and understanding of these unusual rocks. For the researcher, this will be an excellent place to share information with your colleagues. Our goal at Pegmatites International is to serve as a broad primer for more general and specialized study; to serve as a forum for the exchange of information; to review the state of “pegmatology” and address the problems to be solved in the future.
