Jasper is an opaque stone originating from silica rich sediment or volcanic ash. It can occur in any color depending on the mineral content of the original sediment. Beautiful patterns can also occur in jasper. This happens when the original rock- forming materials are fractured or distorted in the ground, and then are later filled in with other minerals. A specific jasper may be named for its location, or may be named imaginatively by describing its unique appearance.

After collecting fossils as a hobby for many years growing up, Dave Douglass opened Dave's Down to Earth Rock Shop in 1970 at the age of 20 (with the help of his parents) at 1312 Chicago Avenue in Evanston, Illinois. The shop contained minerals and fossils, mostly self-collected by the Douglass family.
