Here you go, found this somewhere on gamefaqs, I had saved it to text, but the thread there is no longer active. Trial and error this wont work on everything.
Heres what you do
1.Equip a bow and set of arrows
2.Draw the bow back and while holding the trigger button in press B and go to your weapon select screen
3.Click another set of arrows(ones your not using) and click A on it twice
4.Go to an item you want to clone, dont press A on it, instead drop it by pressing X
5.Go back to your weapons screen and drop any set of arrows you have by pressing X
I havent tested it much, but i believe it works on all stones, such as Varla stones which are sweet, free recharges on enchanted items!
Make sure you do it somewhere where you will be able to see items on the ground easily.
Works on Azura's Star Most enchanted rings I have tried and pendants and necklaces, etc. Works on all armor i think, works on most ingredient items.
Wont work on black soul gems or nirnroot or skeleton key or weapons..
