Jewelcrafting

A player can find gems that can be placed into the socket position of their equipment. Perhaps call it "Jeweler" or something not quite so reminiscent of WoW (new craft going in there). I do like the idea that once a jewel is in a socketed spot it cannot be removed, but a new one can be put over top of it at the cost of the old one being destroyed. Perhaps some bonus that if you match all your sockets with the same color or "gem" or however we do it there is an added bonus.
