Would you buy this? I certainly wouldn't!
People sometimes joke about pouring blood, sweat, and tears into their work. Iceland-based designer Sruli Recht put some actual skin into his.
The Forget Me Knot ring is mainly made of 24-carat gold, but instead of sporting a diamond or an emerald, it has a bit of human skin for embellishment. That skin came from a willing donor, the designer himself.
Recht had a 4 inch by 0.4 inch piece removed from his abdomen. The skin was tanned, complete with hair intact, and mounted to the ring. I think even Sauron would think twice about wearing it.
There's more at the link, complete with pictures and a link to a video about how the skin was removed.
I've yet to think of a single compelling reason why anyone would want to waste their money on something like that!
