Not really at the moment. I'd have to do one completely start to finish on a frame of my own to get an idea on time and cost. I could plate a thick layer of gold onto the frame as well so would take a long time time wear off if it did. Or plate the majority of the frame in a decent layer of gold and build up a thick layer on the tips of the earstems. As the tips of the earstems see the majority of the wear.
The inner orbitals as well (for some people, it touches the brow). It would probably be most cost effective that way as well.
