This mod currently just makes changes to the items required to make jewelry.  It comes in two versions for now.

Version one: Rings with gems now require a silver or gold ring instead of the respective ingot.  Amulets now require one flawless gem and two normal gems instead of two flawless gems.

Version 2: same as above, but amulets and necklaces with gems now require a necklace instead of an ingot

I can make other changes if requested.  If I can figure out how to make the ring meshes use two different textures, I'll also make it possible to use all gems with both silver and gold.  Let me know if you can help me with that, please.  I'd appreciate it, and I know there are mods that do it.
