I bought a 365 nm UV light to unlock forbidden colors in my minerals. Top is my manganoan calcite I got last week at a rock show (most fluorescent specimen I have in my collection, it turns a pink-orange which is pretty cool) and on the bottom is my cassiterite (not fluorescent) but I found that uv light will shine on dust so it was kinda interesting.
The photo I have does not do the fluorescent property ANY justice, it is very bright IRL. Maybe I’ll see if I can take a better photo in the future.
