Fordite cut into a round and set into a sterling silver, plain bezel for a tie tac. It has a chain to go into the button hole. The size is about 3/4″ across. Fordite is from Ford motor company, the paint booths. Each color is a different car and no 2 are alike. It was scraped from the paint booths and tossed in the dump. Thankfully some was taken home and then jewelers discovered it. When it is gone it is gone, cars are not painted the same way today. Colors in this piece of Fordite are orange, red, white, gray and black. We do not get much with orange in it. A great gift for the tie wearer!
