ABC Wednesday: J is for Jasper

John and I went to Gemstone Gems and I learned about jasper for the first time:
Jasper is an opaque,[1] impure variety of silica, usually red, yellow or brown in color. This mineral breaks with a smooth surface, and is used for ornamentation or as a gemstone. It can be highly polished and is used for vases, seals, and at one time for snuff boxes. When the colors are in stripes or bands, it is called striped or banded jasper. Jaspilite is a banded iron formation rock that often has distinctive bands of jasper. Jasper is basically chert which owes its red color to iron(III) inclusions. The specific gravity of jasper is typically 2.5 to 2.9.[2]

  8. So beautiful! I love stones...my grandfather used to tumble rocks and I've always been fascinated by polished stones. Of course I remain partial to obsidian (hehheh!) but jasper is truly an extraordnary one.
