Some Chalcedony will do that possible Nickle Chrysoprase but this is only a guess.

Hi guys thanks for your interest n response. I have just got it tested in GSL Sydney and they say its natural material called ‘‘Strontium Alluminate’’. Very highly fluorescent and unique in specimen form…Thanks

Your material is a ‘synthetic aggregate’, a fake counterfeit of the astonishingly rare ‘YeMingZhu’. Authentic ‘Ye’ (night) ‘Ming’ (bright) ‘Zhu’ (pearl) is the Chinese ideogram for a family of crystals, minerals and gems that glow in the dark.

Thanks for the heads up. More fake stuff to deal with . I should have known ,Chalcedony that fluoresces does it under UV.
