Agate and Jasper Cabochons

This section includes cabs made of agate, jasper, chert, rhyolite, and their varieties ("picture jasper", "wonderstone", "hickoryite", "mozarkite", etc). Free-form shapes are good for making wire-wrap jewelry or simply for collecting.  Standard shapes (e.g., oval) are also good for mounting in various jewelry findings.

What you see is what you get. Item in picture is same one that's for sale.
Each cabochon or piece of jewelry is a unique item.
The material is 100% natural and does not contain any added colors or stabilizers, unless specifically noted.  Normally, agate doesn't need any kind of treatments or resins.  It is a very hard, siliceous stone that takes a nice polish.

Assortment, 4-piece.  Four different cabs / freeforms. 
Left to Right: 
1.) Biggs Jasper (USA)
2.) Missouri Lace Agate (USA)
3.) Indian Blanket Jasper (USA)
4.) Porcelain Jasper (Mexico).

For size reference, the Biggs Jasper oval is about 1 1/16" tall.

All four cabs cut and polished in USA!
