Fordite, 8 cabs were cut from a chunk of Fordite that had been removed from a paint booth at Ford motor company pre 1972. When it is gone it is gone, cars are not painted the same way today. It was dumped into a dump, but thankfully some was taken home and then jewelers discovered it. A new line of jewelry was born! W set our Fordite in sterling silver, various shapes & colors are white, red, blue, yellow and gray. Each cab has a sterling silver lip around it, the rear of each are solid, not open, with a toggle clasp. Will fit 7″-8″ wrist. Each section is about 3/4″ x 1/2″ in size.
