{"product_id":"native-palladium-1","title":"NATIVE PALLADIUM","description":"A single, 1.0 x 0.9 mm wide grain of Native Palladium is mounted in a 16 mm diameter resin polished block. It is from Nizhnii Tagil in Sverdlovsk Oblast, Russia, which is a famous Platinum mining area. This style of polished mount requires a specialist reflected light microscope in order to study the grains and the reflectance produced by metallic minerals under plane polarized and cross polarized light. Often, even optical identification is a challenge and so polished blocks are usually studied chemically using a Scanning Electron Microscope. This is not our usual type of specimen, but included due to its rarity. This sample comes with a previous printed collection label from Austria, but prior to that it was also owned by Dr. Hans-Jurgen Wilke (1925-2014). The overall measurements provided indicate the size of the polished block.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46584887115951,"sku":"CC43646","price":200.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC43646.png?v=1771863367","url":"https:\/\/crystalclassics.com\/products\/native-palladium-1","provider":"Crystal Classics","version":"1.0","type":"link"}
