Here's an instructable from a professional, on this exact topic:

Making a custom Platinum Diamond engagement ring

I could have taken this ring directly into the "lost wax casting " process, but I decided to make a mould first.

Sometimes in the casting process, their may be a casting failure, where the item doesn't cast perfectly. By making a mould, I can create duplicates of this ring.

If the first wax produced, fails to make a good platinum cast, I can simply go to this stage and create another wax model using the mould.

During the "lost wax casting " process, the wax is lost in the process when it melts in the kiln. By making a mould I wouldn't have to re-carve the model should a failure occur.

I use a simple two part RVT silicone moulding compound when I create my moulds.

In order to use the bones system you must use press to make the mold, in this way you can destroy the wax model, anyway you can do several things, 1 make a sand casting 2 make a gypsum mold, aftherthat you can make a casting in this mold. 3 make a wax lost process, afterthat with the first metal model you can make a rubber or silicon mold for make many wax models , with it.

. Ah. Then I have no idea. The only casting I've done was in high school shop class, back in the '70s, and we weren't making jewelry. :)

. Does this help any? If the original is not too complex, a two-piece sand mold may work.
