Common opal is opal the doesn’t show any type of fire or iridescence. Many fluorescent common opal is amorphous and can be discovered as beautiful, sinuous specimens. The common bright green fluorescence is attributed come activation by uranyl ions.

Chartreuse, hardly ever yellow (LW, MW, SW)Common Opal; Virgin Valley, Nevada (SW)


Until recently, pyromorphite no on the fluorescent collector’s radar. Though pyromorphite proper fluoresces under the much more traditional brief wave or long wave lights, some specimens explode with color under mid-wave UV. Additionally, recent finds indigenous China that encompass plumbogummite pseudomorphs together with pyromorphite room truly spectacular under mid-wave light.
