Malachite Azurite Native Silver pseuodmorph botryoidal chrysocolla
Agateyes posted a topic in Rocks & Minerals
Hello all, I need help identifying a piece I was inherited recently. My best guess is a combination of Azurite, malachite, native silver, botryoidal chrysocolla, and some type gemstone imbedded in the azurite main specimen, with who knows what. I could be way off, but I’m going off similar pieces of my collection and knowledge. The top has an interesting metallic botryoidal effect around the main specimen. I am unsure of the location and it has some weight. Thanks in advance for your consideration and assistance, Mike -
Here are two interesting Pennsylvanian fossils that I bought at the Flagg Gem and Mineral Show in Mesa, Arizona (~4.5 inches wide) from the Apex Mine near St. George, Utah hosted in the Callville Limestone. A Chatetes sp. sponge is coated in azurite and malachite. Syringopora sp. coral molds are in goethite with significant germanium and gallium values. The goethite replaced the limestone. See this USGS article about the mine: https://pubs.usgs.gov/bul/1577/report.pdf
