So many nipple clamps, so many nipples to be clamped. Here's a fine place to start. Both are hand-carved black jasper set in sterling silver. One set is the dangly style, with larger jasper designs set at the end of a 2- or 3-inch rod. The other, "non-piercing" type are smaller and clamp differently than the traditional clamp; users actually bend to fit. While this amateur's limited experience with the latter style usually ends up with the things getting busted, but I break a lot of things. Still, the classic style is a classic for a reason: It works. Both look great.
