Forget Me Knot
We all know BioJewellery; two wedding rings grown from bone tissue collected from two lovers. This intimate ring allows you to physically wear your partner around your finger.
Although these rings are very intimate and symbolic they are made of a material (bone) which is quite abstract. Bone is hopefully not something you usually touch and see from your partner.
Sruli Recht, an Icelandic fashion designer, has solved this problem. He created a ring with a slice of his own skin. A piece of rectangular skin is surgically removed from his belly. The skin is then tanned, salted and mounted on a 24 carat gold ring. Sruli also made a short documentary about this process, but beware this contains graphic scenes of the operation.
Although it might give you slight rushes of anthropomorphobia, with this ring you wear a piece of your partner which actually feels like him or her.
