Dumortierit<\/a> ist ein Aluminium-Borsilikat, das in der Regel in blauen bis violettblauen Farbt\u00f6nen vorkommt und oft eine faserige oder k\u00f6rnige Struktur aufweist. Der Stein ist nach dem franz\u00f6sischen Pal\u00e4ontologen Eug\u00e8ne Dumortier benannt, der das Mineral im 19. Jahrhundert beschrieb. Aufgrund seiner auff\u00e4lligen Farbe wird Dumortierit h\u00e4ufig als Schmuckstein und manchmal auch als Imitation von Lapislazuli verwendet.<\/p>\n Gr\u00f6\u00dfere Vorkommen gibt es in Brasilien, Madagaskar, S\u00fcdafrika, Sri Lanka und in den Vereinigten Staaten. Dumortierit bildet sich in aluminiumhaltigen metamorphen Gesteinen und Pegmatiten. Seine chemische Formel lautet Al\u2087BO\u2083(SiO\u2084)\u2083O\u2083 und seine H\u00e4rte liegt zwischen 7 und 8 auf der Mohs-Skala, was es relativ hart und verschlei\u00dffest macht.<\/p>\n Quellen: <\/strong> Der zum Doppelzylinder geschliffene Stein ist in einer silber- oder goldfarbenen Fassung mit \u00d6se befestigt. Der Doppelzylinder hat eine L\u00e4nge von ca. 3,2 cm, gemessen ohne \u00d6se. Diese Anh\u00e4nger sind in verschiedenen Steinsorten erh\u00e4ltlich und werden einzeln geliefert. Aufgrund der Verwendung von Natursteinen k\u00f6nnen Farbe, Markierungen und Verarbeitung von einem Anh\u00e4nger zum anderen leicht variieren.<\/p>\n<\/p>","protected":false},"excerpt":{"rendered":" Dumortierit-Doppelschmetterling-Anh\u00e4nger aus China<\/p>","protected":false},"featured_media":61340,"template":"","meta":{"_acf_changed":false,"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"soort":[],"product_brand":[],"product_cat":[3388],"product_tag":[],"class_list":{"0":"post-61383","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-dubbeleinder-hangers","7":"pa_herkomst-china","8":"pa_maat-32-cm","9":"pa_soort-dumortieriet","10":"pa_verkoopeenheid-per-stuk","11":"pa_vorm-dubbeleinder","12":"pa_vorm-hanger","13":"desktop-align-center","14":"tablet-align-center","15":"mobile-align-center","16":"ast-product-gallery-layout-horizontal-slider","17":"ast-product-tabs-layout-horizontal","19":"first","20":"instock","21":"taxable","22":"shipping-taxable","23":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product\/61383","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/media\/61340"}],"wp:attachment":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/media?parent=61383"}],"wp:term":[{"taxonomy":"soort","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/soort?post=61383"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_brand?post=61383"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_cat?post=61383"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_tag?post=61383"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
