Cannot craft jewelry and yet cannot buy blank ones, 99% of quest reward jewelry do better jobs than enchanted one like 100 times. And there are three armor type glyphs. Move some of those jewelry ones to armor please.
Just re-enchant the jewellery with whatever you want. There are only a handful of items that can't be re-enchanted and I don't think any of them are jewellery.
I have three ravager jewellery pieces on my main right now that definitely do not have their original enchantment ^_^
1. Is it part of a set you need?
2. If not, does it have the base you want (Healthy, Arcane, Robust)?
If the answer to either of those is a yes, then just apply whatever enchant you find useful onto them. Remember that most of those come with a blue or purple enchant value, so you need to go purple or gold to make it better.
Yes! and while they're at it they can port over the skill from Skyrim that lets you put 2 enchants on one item, not to mention allowing you to rename an item when you enchant it ..
