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 stones have been test fired up to 800°C.
The depth of colour is really beautiful and the sparkle is stunning. I cannot wait to include these in a project. As always excellent service and well packaged by Metal Clay Ltd...Thank you
