Occasionally you get lucky on looted ones - a friend of mine gave me a brittle piece that had +15 magery, +15 Disco and +15 wrestling, and about 400 intensity worth of magery related skills.
But Crafting jewelry is still a joke at this point. I have a collection of jewelry with 1 or 2 properties, often at cap or overcap and with high imbue cost, waiting for something to change to make it to where properties would be worth adding. But there's no sign yet.
