My torc came from 6th Night Grove, ADF. I was a member there when I gave my Dedicant Oath, and they recognize their members who have completed it with a Torc.
So, in consequece, I have no idea how much it cost or where they got it from. But I do know that there was a card in the box, noting the studio it comes from. It's from St. Justin (I believe, though I'll have to double check)
I tried looking for it, but I can't find my Torc online. This is the closest I can come:http://mystic-caravan.com/pewtorc.htm
Obviously, this one doesn't have the copper and silver mine does. And it's hinged, which mine is not.
*sighs* I don't have any idea where to find it. I'll see if I can check with 6th Night (if I remember to).
