{"id":86,"count":3,"description":"CLASS: Nesosilicate . . . CHEMICAL FORMULA: (Mg,Fe)2 (SiO4) . . . CRYSTAL SYSTEM: Rhombic\r\nCRYSTAL FORM: prism, pinacoid, rhombic bipyramid; rounded corners\r\nIt comprises an isomorphic series from Forsterite (Mg2 (SiO4)) to Fayalite (Fe2 (SiO4)).\r\nCOLOR: olive green or yellowish, brown, red.\r\nThe transparent green variety is called Peridot, used as a gem.\r\nPHYSICAL PROPERTIES: hard (6.5\/7 Mohs), heavy (3.30\/4.20 g\/cm3), increasing density to a higher proportion of Iron (Fe), fragile, with conchoidal fracture, transparent\/translucent, vitreous\/greasy luster.\r\nOlivines rich in Magnesium are characteristic of magmatic rocks. It is also present in some Meteorites and in rocks of the Moon.\r\nCURIOSITIES: it is related to the power of regeneration, leaving behind the negative.\r\n","link":"https:\/\/www.mineralitum.com\/en\/buy\/olivine\/","name":"OLIVINE","slug":"olivine","taxonomy":"product_cat","parent":0,"meta":[],"_links":{"self":[{"href":"https:\/\/www.mineralitum.com\/en\/wp-json\/wp\/v2\/product_cat\/86","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.mineralitum.com\/en\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/www.mineralitum.com\/en\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"wp:post_type":[{"href":"https:\/\/www.mineralitum.com\/en\/wp-json\/wp\/v2\/product?product_cat=86"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
