My Dad was one of the first mass producers of Liquid Crystal jewlery first invented by Josh Reynolds in 1975. I have several rings left from long ago that I am selling. I have no packaging for these rings, so they will arrive in a padded envelope, and I will put tissue paper around the ring. These rings were made many years ago, so please give them a minute to change colors. They all work. Liquid Crystal changes colors through heat, so if your hand is cold, the ring will not change colors at all. Please feel free to message me with any questions. All the rings are approximately a size 7, but they do vary here and there and do not adjust. There is a plain edge and a decorative edge. Please note which one you would like. I will send the plainedge by default beginning onAugust 24th, 2023.
