Hi, Guy– Feldspar (typically microcline) fluorescing dim maroon is commonplace. I just read in Manny Robbins' new book on Fluorescence that this fluorescence becomes bright when it is chilled enough. The zektzerite may fluoresce as bright as that opal, but I will wager it is not the same green color. The books describe it as "white"; I suspect Lanny's mention of "bluish" is also zektzerite, a variation on white. –Doug
