All the Spiral jewelry you see here is hand made and unique. I take great care to give you the best product each and every time. Also I make each and everyone of these spirals from real sterling silver. The extensive finishing, forming and hardening is all done by hand in my home shop in northern CA where I live. The smallest Gauge wire I use for the spirals is 16. Slightly larger than the standard 20-18 gauge ear wires used with most earrings. these earrings are extremely comfortable and stay in well. these are not wimpy or crude earrings. also available in 14k gold, $125. per pair.
