You are looking at 2 green Alunite cabochons. The total weight is with a thin layer of backing. The sizes all vary with the penny shown at 19mm for reference. They were freeform cut and have a good shine. The stones shown in the picture is the ones that you will receive. Thanks for looking and take a look at my other items!
