Under UV it shows a little green, but I'm using a really bright UV light in the photo, and it will not glow green like that. See the darker photo with the pale blue. Not sure if it always glowed like that, when new, but today they all have the pale blue glow. The hands and dots do not glow at night, but show up great under UV.
Their luminescence has long since expired. When I pass my UV flashlight over it, it draws a line where the light shown that slowly fades. It's a very unique piece.
