Green acicular crystals of Arthurite in 1mm clusters. This specimen comes with a label from the Jack Parnau collection. Originally the label stated that only Arthurite is on the specimen. But, Parnua hand-wrote "Parnauite" on the specimen also. I looked around with a microscope briefly, and I saw no Parnauite. See prov. tab for Parnau label.
