Vintage UV Reactive Stretch Bracelet Yellow-Green Glass Stones (Uranium?)

This is a gorgeous vintage bracelet. I'm guessing mid-century; it's a stretch bracelet with greenish-yellow glass stones set in silver-toned metal. The glass stones are UV reactive; they glow bright green when put under a blacklight or UV light. I'm not sure if they're uranium glass, manganese glass, or something else, but they glow beautifully under a 395 light (photos were taken under a 395. it has a very faint glow under a 365) The bracelet is in excellent condition, and it will come in a gift box.
