I love the rich yellow colour of this gem and they fire really well in the fine silver clay. I normally fire them for thirty minutes and they come out the same way they went in. Service as always with Metal Clay Ltd is excellent.
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 are test fired up to 800°C
