Osiris is made with a stone I have found myself. I think it is calcite, it has a beautiful cream white colour with some details inside and even tiny rainbows. It had this shape when I found it but I finished up the sides a bit and also sanded the front to make it smooth.
The setting is clay and the texture is sand, painted in acrylic paint. The bail is blackened iron. Comes with leather or satin cord.
