An individual stone, either natural corundum, lab grown corundum, or cubic zirconia. Push them into the wet clay, and fire with the stone in place. Beautiful stones - they are top quality cut.
All of our kiln-safe gemstones are test fired up to 800°C
Super sparkly. So beautiful. Cant wait to start creating birthstone rings with these. I have also added the smaller ones (fireable) to wet clay and fired them. They come out perfect.
