For fans of the radioactive minerals (but how do you get them past Homeland Security?) the Severino/Celmira dealership (firstname.lastname@example.org) had several flats of bright yellow and green meta-autunite and uranocircite
from Aideia Nova, Satau, Portugal.
However, they are extremely lustrous, and with vivid colors suggesting where each one is on the compositional zoning continuum: bright apple-green means that meta-autunite predominates, whereas grass-green means uranocircite
. The little crystals form bright drusy carpets on gray quartz matrix pieces mostly between 3 and 10 cm wide.
