Hello my fellow inhabitants of Skyrim!

I had a question regarding the selling of jewelry. For some reason I can't sell my enchanted rings and necklaces as well as regular gold and silver rings and necklaces to vendors. I have tried Medesi (the jewler) in Riften as well as General Goods stores such as Riften's Pawn Shop, Whiterun's General Store and the Riverwood Trader. It is annoying because I have so much it clutters the items menu. It's not that the vendors don't have enough gold, but the jewelry just does not appear in the drop down menu to sell items. Is there a reason for this?

Thank you!

Is it stolen? If it is it won't show up on your inventory when trying to sell.

Ah yes, it is stolen! Where can I sell such stolen goods?
