Vintage UV Reactive (Potentially Uranium Glass?) Green Cabochon Flower Brooch

This is a vintage flower brooch made out of green cabochon stones to form petals. Using a Presidium Gem Tester II, the stones test as glass. The stones are UV reactive (potentially uranium glass). They look like a deep olive green under normal light, but they glow bright blue-green when exposed to a UV light or blacklight (the photos were taken under a 395 blacklight). It also glows under a 365 light, but the glow isn't as vibrant). It would look beautiful displayed in a curio cabinet full of UV reactive like like uranium, manganese, or selenium glass. The brooch measures 1.75". It's in good condition; the pin has a minor bend in it, but it's still wearable, and it will come in a gift box.
