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]

    I've always loved jasper. When I was a child, we tumbled rocks and the jasper just lit up the other stones. Nice post!

    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.

    I love gemstones! Thanks for all the information about Jasper! I knew it was a chert, but not much else. :)

    I love gemstones and jasper is one of my favourites as it is so colourful. That photo of all the jasper necklaces is so pretty.
