I'm currently banned from making & wearing stone-set signet rings and chunky chain bracelets; I'd probably be allowed a plain signet ring, but if I can't set it, I'm less interested.
Cufflinks are OK.
Heavy necklace/necklet chains I've seen worn effectively, usually the surfing/diving brigade.
Celtic & tribal designs seem to be quite popular, as do some of the Chinese glyphs (probably best to steer clear unless a) you can paint them and b) you're sure it isn't a menu item)
Delicate isn't going to cut it; a semi-industrial look probably works better.
Now, if I only had the time to make some cufflinks for myself... Working on some mokume gane ones at the moment.
