25x18mm Green Copper Matrix Collage Cabochon Oval Flat Back Stone S2205D
You are purchasing the exact stone you see in the photo. This is a single piece. This stone is what we call a matrix stone. It is man made. I use this term to refer to stones created out of small pieces of material, then bound together with a very hard stone like compound. Something like a very hard resin. You see this type process used in fancy granite, marble or stone counter tops.
