33 Quartz Q 1560 under flash
Quartz from unknown location that I obtained somewhere (most likely in Tucson in 2011).
34 Q 1560 under SW
This specific quartz specimen fluoresces bright orange, SW, duller MW, and is dead under LW350 or LW370. Do you have any idea where this specimen could have come from?
