Fordite is from pre 1972. It was from Ford motor company. The workers had to peel it off the walls & pipes of the paint booths. Then it was tossed into a dump! Thank goodness some was taken home & then jewelers discovered it. When it is gone it is gone, cars are not painted the same way today. Each color was a different car and never 2 pieces alike. We set this piece of Fordite into a sterling silver ring size 10. Would be great on the middle finger or ring finger. It is solid on the rear of the Fordite, not open. A small shoulder of sterling silver is on both sides of the Fordite. Size of this free form is about 3/4″ x 1/2″.
