Prehnit<\/a> ist ein blassgr\u00fcnes bis gelbgr\u00fcnes Mineral, das h\u00e4ufig in runden, kugelf\u00f6rmigen Aggregaten oder als Krustenablagerungen auftritt. Es hat einen glasigen bis perligen Glanz und ist teilweise durchscheinend. Die Farbe wird gew\u00f6hnlich durch Spuren von Eisen verursacht. Prehnit wird manchmal als Edelstein verwendet und ist bei Sammlern wegen seines unverwechselbaren Aussehens beliebt.<\/p>\n Das Mineral wurde erstmals in S\u00fcdafrika entdeckt und ist nach dem niederl\u00e4ndischen Oberst Hendrik von Prehn benannt. Gr\u00f6\u00dfere Vorkommen gibt es in S\u00fcdafrika, Australien, Schottland, den Vereinigten Staaten und China. Prehnit bildet sich in der Regel in Hohlr\u00e4umen von Vulkangestein und ist ein Produkt hydrothermaler Prozesse. Seine chemische Formel lautet Ca\u2082Al(AlSi\u2083O\u2081\u2080)(OH)\u2082 und seine H\u00e4rte liegt zwischen 6 und 6,5 auf der Mohs-Skala.<\/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":" Prehnit-Doppelschmetterling-Anh\u00e4nger aus China<\/p>","protected":false},"featured_media":47967,"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":"default","adv-header-id-meta":"","stick-header-meta":"default","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","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-47956","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-prehniet","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\/47956","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\/47967"}],"wp:attachment":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/media?parent=47956"}],"wp:term":[{"taxonomy":"soort","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/soort?post=47956"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_brand?post=47956"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_cat?post=47956"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_tag?post=47956"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
