My Mineral Collection, Introductory Page

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 images tend to come out a little redder than they appear in person.

I've been collecting since I was a kid and I'm finally starting to specialize (a little). Garnets will probably always be at the top of my list. I'm also interested in the oxides (spinels, rutile, etc.), sphalerites of good color, metal ores and sulfosalts (copper, lead, zinc, etc - the chemistries and colors are fascinating), and good crystallizations in general. I also like specimens with mineral associations (like this Morenci mixed copper ore.). Finally, I like optically interesting specimens.

Pride of Place: All of my specimens have been obtained for one reason or another - they may not all be pretty and may only be here because of their rarity or chemistry or technological importance. Some of the more esthetic ones will have purple borders and Type Locality specimens with have gold borders (and some will have both).

There are lots of images so I've decided to split them into multiple pages covering different parts of my collection. Like most amateur collections, mine's in two parts - the first set of pages covers minerals that are grouped by function (gemstone, copper, lead, and zinc minerals) or mineral type (quartz, fluorite, calcite, pyrite, and sphalerite) because I have a lot of specimens in those categories. The systematic (chemical) arrangement is more scientific and I generally have fewer of those (except for the silicates). The images on each page are in alphabetical order, older specimens first, varietals last. I try to follow the newer Strunz classification (rather than Dana) scheme.

The uncredited specimens have either been dug up personally or purchased at various mineral shows (like the formerly annual Carnegie Gem & Mineral Show) and "rock shops".

Garnets are one of my favorites so they're first! For some general info on garnet types and varieties, please see my miscellaneous garnets page.

These are some of the field guides and mineralogy books that I have.
