I've got a special stone for you guys today!!! Opalina I believe it is also called Peruvian blue opal. I personally don't know a lot about it but when I saw it at the gem show this year I knew I had to have some. I have to stabilize the rest of it before I attempt to cut it but I'm taking requests for cabs.#opalina #cabking #cabsforsale #huggerlapidaryandjewelry #stonestogemstones
