Lab Fluorite Facet Rough Blue Glow Scintillator, Color Change chain This material is supposed to

This material is supposed to fluoresce (so they can see where the x-rays in the machine are going)

best visible under 365nm UV but it also reacts to 395nm as well

This is one of my favorite designs that I've come up with--I had the idea over a year ago but finally got it into a workable form and have had some cut and set

They aren't radioactive anymore but each is a small piece of history

We have colorless sapphire grown for technical use (like lenses and sensor windows)

Lab Fluorite Facet Rough Blue Glow Scintillator, Color Change chain This material is supposed toThese are lab created hyperfluorescent blue fluorite facet rough. The glow from these Eu: CaF2 crystals is so bright the camera has trouble depicting an accurate color while it's a pure blue to the eye, the camera will saturate early and start depicting it as purple or cyan instead. This is fluorite, a most unusual gem. Natural material is known for its incredible range of colors, as well as for some specimens that show very strong fluorescence (hence
