{"product_id":"pyromorphite-plumbogummite-yangshao-mine-china","title":"Plumbogummite pseudomorphs after Pyromorphite, Yangshuo Mine, Guilin, China","description":"\u003cp\u003eI remember when the mineral market was stunned when these incredible plumbogummite specimens started arriving from China. Prior to 2014-15, plumbogummite was relatively unknown to the greater market but the Yangshuo Mine specimens changed that. Plumbogummite is a rare phosphate mineral that forms after the oxidation of lead deposits. At Yangshuo, plumbogummite has replaced and retained the form of pyromorphite (a lead \u003cem\u003echloro\u003c\/em\u003ephosphate) so they are pseudomorphs (\"false form\"). This example shows the pseudomorph process in transition. The original hexagonal pyromorphite is a wonderful, vivid yellow-green. Those crystals showing a pale \"robin's egg\" blue have transformed into plumbogummite making for a very colourful sample. This colouration, along with its size, make a bold statement. From Rob Belcher's collection. From: Yangshuo Mine, Yangshuo County, Guilin, Guangxi Zhuang, China. Dimensions: 9 cm x 7 cm x 5 cm\u003c\/p\u003e","brand":"Rocky Mountain Minerals and Fossils","offers":[{"title":"Default Title","offer_id":52347133395226,"sku":null,"price":375.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6011\/1386\/files\/IMG_5053.jpg?v=1781284246","url":"https:\/\/keithrocks.ca\/products\/pyromorphite-plumbogummite-yangshao-mine-china","provider":"Rocky Mountain Minerals and Fossils","version":"1.0","type":"link"}
