{"product_id":"tyrolite-and-azurite-on-siderite","title":"TYROLITE and AZURITE  on  SIDERITE","description":"This stunning old-time Tyrolite specimen from the Tyrol region in Austria is a true European classic. It is not from the Type Locality, but another in the vicinity, but dates to a very early period. We know this because it is accompanied by a lovely old handwritten German\/Austrian label dating to the 19th century. It uses the original 1816 term - Kupferschaum - alongside Tirolit, showing the transition in nomenclature. Small cabinet in size, the display surface is covered in a combination of very glossy dark blue microcrystalline Azurite but with feathery sprays of pearlescent blue-green Tyrolite reaching 6 mm in diameter displaying their classic almost plastic-like lustre. Underneath this the matrix is massive Siderite. It is from Kogl, or Kogel, a hill to the south of Brixlegg in the Tyrol. It is from the superb systematic collection assembled by the brothers Martin and Michael Günther (1951-2007 \u0026amp; 1956-2021).","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781196292431,"sku":"CC27731","price":1110.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC27731_34b37436-9a95-4dbc-9310-8d4208c2bb26.jpg?v=1783981475","url":"https:\/\/crystalclassics.co.uk\/products\/tyrolite-and-azurite-on-siderite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
