Some jewellery can be enchanted some cant be.
What determines what can be enchanted and what can't be, I have wasted money on rings and necklaces only to find they can't be enchanted, then crap I don't want that's no use to me, says you can enchant it.
Is there a system or something I need to know, so I stop wasting money buying jewellery that I can't enchant
Just such a poor design.
