The clay that I used to made these beads was dug from right here at Luna Parc. We found a clay vein under the roots of a tree that had toppled over. The clay is very smooth and makes very nice beads. I used my own glaze formula, Roman Turquois which I use on the sculptures and tiles mounted to my house. The beads are mounted on a sterling chain and the spacer beads are also sterling. This features a large S-clasp. This measures 20" in length.
