"This stone is an absolutely beautiful stone! I embedded it in PMC Flex using the "Bezel Template Square 2." I followed the directions in the "PROJECT VIDEO: JEWEL STAMP PENDANT 2 WAYS BY LISEL CROWLEY." (I used the 9mm template for the outside of the bezel, making a narrower bezel.) I used two different texture tiles to texture both the front and the back of my pendant. I fired the stone as recommended on the downloadable Gemstone Firing Guide sheets with perfect results. I am very inspired by the results!"
