It's My Scar is a website that will turn photos of your scars into jewelry. There are bracelets, rings, and necklaces.

Here's part of one story:

To me [scars] are visible symbols of the events we have experienced, an incredible reaction to our environmental interactions. On more than one occasion I have too eagerly inquired about the scars others have, or don’t have. (I dated a guy once who did not have a single scar on his whole body. I remember thinking “Haven’t you ever fallen? Where is the proof?”) Scars began to find their way into my healthy appreciation for body modification, and in my own art as I pursue my deep appreciation and curiosity of the body.

So it was on one stormy Halloween night (don’t make too much of that) that a”friend” of mine and I decided to participate in a scarification ritual. For me it was to be an annual marker, an eventual segmented band around my arm, to grow over time. We had discussed what and where was to pass, but despite our preparations and discussions he took the opportunity to slash me. I was unprepared and looking away in mid-sentence when he swiped the blade across my upper arm. It was the deepest cut I have ever seen in my life. I was staring at my muscle, all fat peeled back in layers, blood and pain all over my world.
