Uranium glass rosary vaseline glass beads vintage. When buying, please note that the pattern of the metal sheet depicting the saints is always unique and not the same as in the picture! Unique handmade jewelry. Under the influence of UV light, the uranium oxide that gives the glass its color glows in a ghostly green light. Please check my other items! The beads come from a craft manufactory in the Czech Republic, I guarantee their originality. The delivery is traceable, the delivery time is usually a maximum of 10 working days. (Less in Europe, more for the rest of the world). If you have any questions about the product, feel free to ask.
