{"product_id":"vivianite-5","title":"VIVIANITE","description":"Some of the world's best crystals of Vivianite, a hydrated iron phosphate, have come from mines in the Potosí Department, Bolivia. This large miniature, to small cabinet crystal spray, consisting of large, bladed, monoclinic Vivianite crystals with a small amount of orange-red mudrock matrix comes from the Tomokoni mine, Machacamarca District. The Vivianite crystals reach over 6.5 cm in length and several are really well-terminated, with sharp, undamaged edges, and a glassy to slightly resinous lustre. Their colour is a very dark green, but this becomes paler when backlit due to the translucent nature of Vivianite. A really fine example of large Vivianite crystals from a classic occurrence.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46584054415535,"sku":"CC15031","price":300.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC15031.png?v=1771842509","url":"https:\/\/crystalclassics.com\/products\/vivianite-5","provider":"Crystal Classics","version":"1.0","type":"link"}
