1" Yellow-Green Autunite Crystal Cluster - Hunan, China
This is a small cluster of yellow-green autunite crystals that was collected from the Nanjingqiao U deposit of Hunan, China. Under short and long wave UV, these crystals exhibit brilliant lime green-yellow fluorescence.
Autunite is a yellow-green phosphate mineral that often forms in fan-like masses or as tabular crystals. It is classified as a hydrated calcium uranyl phosphate, containing uranium in its chemical formula. Most autunite specimens are highly fluorescent.
While autunite does in fact contain uranium, its risk level is considered low since only a small amount of uranium makes up the crystal. That being said, autunite can lose water and convert to meta-autunite. That along with the uranium content is enough incentive to store specimens in closed containers and away from direct contact with other minerals.
