I have no experience with selling Copyright rights in jewelry design
but I can tell you how it works in a few other situations. In
software and industrial design the contract virtually always calls
for the assignment of any and all Copyright rights to the party
contracting to have the work done and the party doing the work gets
paid either some agreed upon amount or at their standard hourly rate.
I'm sure that's not what you want to hear.
In the publishing field it's a little different but also widely
varied. Not uncommon is for the ghost writer to assign all Copyright
rights to the party contracting for the work but for the hourly
"rate" to be generous (somewhere in the $50 to $100/hour range is not
uncommon). ("Generous" depending on your perspective, of course.) But
these kinds of deals vary a lot depending on who is putting the deal
together and who will be selling and to whom too, could be the
writer, the "author" cited on the work, or a third party with any or
all taking some selling responsibility.
In commercial photography the deal is almost always that all
Copyright rights are assigned to the party that commissions the work
but in personal commissioned work the photographers have got
themselves a pretty good--for them--(in my opinion) SCAM going
against the naive public and are totally claiming all Copyright
rights for themselves so they can continue to charge exorbitant rates
for copies down the line or replacements if ever needed.
Hope that helps. I'll be interested in hearing about real jewelry
deals too. (My guess though is that most fall into the
