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.
Beautiful and sparkly yellow pear shaped stone. I am based in Australia and hard to find good quality stones. This could easily pass for the real deal. The whole order and delivery process was seamless and efficient. Highly recommended.
