Fordite pendant necklace, set buy in sterling silver

This fordite pendant necklace is handcrafted from sterling silver & raw fordite. I cut, formed & polished the piece of fordite. I then made the bezel and back plate, after those were soldered together I used my hand saw to remove part of the back plate so that you can see the colors there as well. This pendant also comes with a 20 inch sterling silver chain necklace.
What buy is fordite?
It's overspray from painting the SUV's at the assembly plant. The layers build up and eventually get removed. I cut, polish and hand forge everything. I also added a picture of what fordite looks like when I purchase it
