Czech 50-Piece Glass Beads, 6x9mm, Teardrop Siam Red

I bought these beads as they are uranium glass and I wanted a dish or jar of them in my UV rective glass display. They glow very brightly under 365nm UV and really catch the eye. As far as the beads themselves, they have excellent clarity and uniformity of size. The color, both under normal light and Uv, is excellent. These were a fun addition to my display and one could make nice jewelry from it as well.First pic is just these beads. Second one is these beads on top of some Michael's crafts UG beads.

I got these to use with my geiger counter. They did register clicks. They also glow beautifully under my infrared flashlight.

They are nice but not fabulous

It's actually uranium. It worked well for testing my geiger counter and I'll keep it around so that I can always check to make sure the geiger counter works.

Beautiful uranium glass, she loves it. Radiation count's 3x higher than background. Still plenty safe to wear, however.

Fluoresces nicely under UV and mildly radioactive at about 3 times the background exposure, reading about 0.5 uSv/h. I wouldn't use these for jewelry.

Used one of these as and angler fish "lure" in a clay sculpture I made and it looks fantastic! Very happy with the quality

Sets off the Geiger counter. Glows bright under UV light.
