Okay so QUESTION:
I recently obtained a blue kyanite crystal with mica and in the store it was mostly blue with some of the black mica properties but by the time I got it home it was completely black.
what caused this and is there anything I should do?
Ask the store what kind of lighting they use.
Kyanite can show blue fluorescence under UV light. I imagine a gemstone store might rig some UV lamps to better show their products. You can get such lamps. Try this on Google: "UV Lamps and Cabinets for Viewing Rocks and Minerals"
I am hoping it is just the light, will look into getting a light to hang with my case , thanks for the input
