{"product_id":"smithsonite-296","title":"SMITHSONITE","description":"This rather unusual Farnberry mine Smithsonite displays the typical, and uninspiring rusty 'dry bone' form, but unusually it is overgrown by a layer of the much more desirable botryoidal Smithsonite. This combination, or paragenetic sequence, is so rarely preserved in Farnberry specimens. Interestingly, the initial deposition of botryoidal Smithsonite is grey-white, with the classic yellow colour only commencing in the very outer 'skin'. Under magnification this colour shift is really striking. Originally in the W [Bill]. F. Davidson Collection (1907-2002), who most likely collected it, he sold his collection to Minerals Unlimited (Scott Williams, 1924-1997) during the 1960s or 1970s, ex Harry Caral and ex R. Hauck (in 1983).","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":47003392639151,"sku":"CC60204","price":600.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC60204.png?v=1780566014","url":"https:\/\/crystalclassics.com\/products\/smithsonite-296","provider":"Crystal Classics","version":"1.0","type":"link"}
