Description
AutunitePresumed Assunção Mine, Aldeia Nova, Ferreira de Aves, Sátão, Viseu, Portugal
7.8 x 6.2 x 3.3 cm (3.07 x 2.44 x 1.30 in)
Among radioactive mineral species, Autunite is a perennial favorite for its intense fluorescence and vibrant color, and this specimen is an excellent representative of the type. Hundreds of well-defined, bladed crystals are tightly clustered across a relatively flat matrix, exhibiting a rich greenish-yellow hue. The crystals are sharply formed and have a sub-vitreous luster, creating a visually cohesive and radiant surface that brilliantly fluoresces lime-green under UV light. This piece is in excellent condition.
More Information: This is a uranium-bearing mineral that exhibits moderate natural radioactivity. It should be handled with care. Avoid ingestion, wash hands after handling, and store in a sealed container to minimize the spread of particulate material.
