Point of note:
Today "Jasper" is often an all- encompassing term applied to numerous stone types that did not enter the market through the old traditional lapidary channels. Red Creek
is most likely a silicated Dolomite with a hardness of between 4 and 5.5. Also, like a number of semiprecious gemstones, because of its natural, inherent fractures and softness, this material, like Turquoise, many times is stabilized.
Jaspers, Dolomite and other sedimentary rocks are in general formed from sediment laid down in ancient seas. Because of the randomness of material in this sediment, when the stone hardens it can be anywhere along a "jasper / not jasper spectrum" of rocks, based on its silica percentage. In the case of Red Creek, it's a little more Dolomite than Jasper. This silicated dolomite is a little harder than its cousin, marble (Picasso Jasper) and every much as beautiful, plus it's more colorful.
