These I believe are from the 60s or 70s. They were on an old lamp that I revamped. I only have 3. The rest of the crystals were clear and did not glow. These have a greenish gray appearance in normal lighting but under 395 uv light they glow a gorgeous radioactive green. With these being vintage there are some chips and one has an air bubble. Please inspect all photos. A little bigger than 3 inches including wire hook. Use these to finish your chandelier or lamps or repurpose. They are truly gorgeous! 🐈 🐕 🐢 friendly home!
