Second - READ DESCRIPTION 25x18mm Malachite with Silver Threading Cabochon Gemstone S4213D

This particular stone has a chip off the edge. Not that big a deal as you can see it looks pretty much normal in the main photo. If this is going in a bezel setting will not matter at all. This is natural malachite that has what I am calling silver threading.  I thought it was a fairly interesting stone. I think perhaps the silver is actually acting as a binder or filler. Not sure. Sort of a less expensive Malachite Cabochon. Perhaps because it is assembled from smaller pieces. Just my speculation. Looks good though.
