Ex. David P. Wilber Collection

A very nice  specimen of sharp, brilliant yellow-green meta-autunite crystals to ~7 mm. on minor smoky quartz 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 one for this find!
