Neat Images for Earth Materials

Sands of the World
Fantastic close-up images of sands from all over the world. This area of the site is lacking in text, so for explanations about the nature and composition of sand grains, please read the rest of this website and consider exploring this site in addition.

The Mineral and Gemstone Kingdom Image Gallery
Sophisticated site featuring a glossary and an image gallery that includes hundreds of mineral photos, catalogued alphabetically. This site also aids in identifying mineral samples from results of color, streak, and hardness tests and visual observation.
