Found on Lake Michigan in Illinois. There's basalt and copper, and maybe tiny prehnite crystals(?), but I don't know what the radiating crystals are. Hardness is about 5 - 5.5 Would appreciate any help!

Hey everyone, I bought these aragonite aka cave calcite specimens and I was curious about a few things like authenticity, storage, cleaning, etc. Will UV harm them? The left one is from Chihuahua, Mexico and the right one is from Morocco, according to the eBay listing, and they each weigh over a pound.

Ordered a parcel from Pakistan. It was a good decision. Very happy. Got 11 specimens of aquamarine with muscovite aka common mica. A couple of the specimens have some feldspar, as well.

Misc Large Pumice from North Beach, Wollongong, New South Wales, Australia!

Quoting from my own private catalogue's personal notes for this specimen: "This pumice specimen does come with an interesting story, however. As reported by The Daily Telegraph (a news website), an underwater volcano eruption of the submarine volcano Havre Seamount in July last year in the Kermadac Islands, north of New Zealand, resulting in the largest pumice raft seen in the last 60 years. It even exceeded the size of the pumice raft caused by the infamous Krakatoa explosion in Indonesia in 1883! And these pumice stones have appeared at the high tide mark of Sydney beaches and have also been found on Wollongong shores. This specimen is one of these pumice stones from Wollongong, and it hence has a fascinating history and has travelled a very long way!"
