Jump ring or lobster clasp

Shop notes, not star ratings, from the International Gem Society findings lessons. The join is the finding that connects one piece of a dangle to the next. Read a hang from the top: ring, then plate, then letter. The starter underneath still needs a closer. IGS: a jump ring has an opening along the ring. Twist it open, slide on a chain or a plate hole, close it. IGS names the lobster clasp as the strongest type of clasp, with a lot of metal in the pincer. A finished chain normally has a clasp at one end and a simple ring at the other that slips inside the clasp. A split ring is a double circle of wire, like a key ring: slower to change, harder to lose. A spring-ring is the lighter closer; IGS notes the spring can stick. A hook-and-eye is a poor match for bracelets because it can unhook in wear. Dangle kits live under Kits. IGS is the public naming; a park-week yank is the local test.

Jump ring

A connector through a plate hole. Unsoldered jump rings can open under strain. Solder if you do not want it to pull apart. A split ring is a double circle of wire, like a key ring: slower to change, harder to lose. Swap a jump ring onto the wrist closer and a lobster onto the plate hole and the jobs no longer match.
