A very nice  specimen of sharp, brilliant yellow-green meta-autunite crystals to ~8 mm. on albite matrix from the major ~2014 find at the Assunção Mine, Aldeia Nova, Ferreira de Aves, Sátão, Viseu, Portugal. Good examples odf this material have become hard to find as they were eagerly snatched up by collectors at the time of the discovery. Super super bright green fluorescence under U.V. light. From the noted collection of David P. Wilber. Nice 3-dimensional one for this find!
