I woke in the night remembering that I had this Jeep Collins hammered brass necklace. I had a piece that dangled from it and I don't even remember what that was.
But look look look how perfectly it holds my pendant!
I'm not a big jewelry wearer, but I can do this.
I still have several pendants available in my shop.
And here is a site that has some variations of this necklace.
And here is an Etsy that has one.
