What is this rock?

I thought this was amazonite with Quartz but under UVC light it reacted unlike anything else i have.

I noticed this was your very first post - so, Welcome Aboard JenniferS! You didn't list your state (or country) in your profile. So, you might consider jumping over to Sub-Forums: Select Your Area.... and selecting location information (i.e., clubs, hunts, finds, legends, maps, etc.) directly related to your state (or country). You might also consider adding your state (or country) to your displayed profile (SETTINGS -> EDIT PROFILE) so if you ask a question, etc. - people may have more success helping you (your location may help, etc.)...

No idea what it is, but that is a very cool looking rock under the UV!!

Your likely correct, quartz and amazonite. The quartz is whats reacting to the UV light with the green glow. I've had some quartz that glows briefly after the UV is removed. Nice specimen

I agree with DDancer, quartz/chalcedony often has rare earth elements in it causing the reaction. Usually green is from uranyl ions (dont worry it isn't radioactive ) - here is some silicated chrysocolla I have that does the same thing. Only reacts under short wave, no reaction to long wave

Pretty cool specimens.
