Copper, while less expensive as a material than silver, is exponentially harder to cast and has a very large loss rate during the process. That means that a large number of those hand cleaned and inspected wax pieces are lost.
A note on sizing: Starlingear rings are all hand sized and therefore will fit different than mass produced 'cookie cutter' rings. The size listed is the best fit. Any competent jeweler can 'stretch' the ring up a half size or so. Going up drastically or down in size will require some more skill.
