Stone Rings (7)The stone rings that I designed are more versatile than most. The edges are well rounded and the insertion gap between the ring is slightly larger allowing the rings to be worn in areas like septum, conch and nipple piercings as well as others not typically suited for small insertion gaps. Of course you can always wear them in the earlobes as well! Stone rings are available in sizes 8g through 00g. The inside diameter on sizes 8g-2g is 1/2" and 0g-00g is 5/8".
