I just noticed a few of my purple/pink sapphires from Montana have a distinct red glow in LW UV. These are untreated stones, 0.4-0.6ct  |

I have a few small blue saphires from Mason's and they also fluoresce pink under 365 long wave.

Perhaps there's some chromium in that blue? I have one cut blue that's slightly red under LWUV. This might explain why the blue leans towards purple. |
