I’ll be honest, I do not know very much about this lot. These are various jewelry mold of rings and molds of pendants. These came in very old cases. I did have to throw out some of the inside of the cases as it had disintegrated, 16 of these cases will be shipped along with the jewelry molds Thanks for looking. Some of these cases do have some stamps that say Classic Industies Culver City, California on them. I’m not sure if that might mean something to somebody. noticed last picture one ring did break while I was packing so I will not include. One of the cases is also broken. Cases are antique and do need to be cleaned. One case is slightly broken.
