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> Unsere Halsketten sind in verschiedenen Ausf\u00fchrungen erh\u00e4ltlich, darunter facettierte, kugelf\u00f6rmige, geteilte und geknotete Halsketten. Derzeit sind alle Halsketten in unserem Sortiment 45 cm lang, was einer Standardtragel\u00e4nge f\u00fcr die meisten Halsgr\u00f6\u00dfen entspricht. Die verwendeten Perlen oder Splitter variieren in Form und Ausf\u00fchrung, was jeder Kette einen einzigartigen Charakter verleiht. <\/p>\n Die Gr\u00f6\u00dfe der Perlen variiert je nach Art der Kette, von etwa 4 mm bei den feineren Modellen bis zu etwa 8 mm bei den etwas gr\u00f6beren Ausf\u00fchrungen. Bei gespaltenen Ketten werden ungleiche Steinst\u00fccke verwendet, wobei die Spaltung zwischen 5 und 10 mm variiert, was ein nat\u00fcrliches Aussehen ergibt. Bei geknoteten Halsketten wird ein Knoten zwischen den Perlen angebracht, der nicht nur dekorativ ist, sondern auch zur Festigkeit des Schmucks beitr\u00e4gt. <\/p>\n Beachten Sie, dass nicht jede Sorte in allen Designs oder Perlengr\u00f6\u00dfen erh\u00e4ltlich ist. <\/p>\n<\/p>","protected":false},"excerpt":{"rendered":" Prehnit Split Halskette aus China<\/p>","protected":false},"featured_media":53643,"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":[3025],"product_tag":[],"class_list":{"0":"post-53674","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-splitkettingen","7":"pa_herkomst-china","8":"pa_maat-45-cm","9":"pa_maat-split","10":"pa_soort-prehniet","11":"pa_verkoopeenheid-per-stuk","12":"pa_vorm-ketting","13":"pa_vorm-splitketting","14":"desktop-align-center","15":"tablet-align-center","16":"mobile-align-center","17":"ast-product-gallery-layout-horizontal-slider","18":"ast-product-tabs-layout-horizontal","20":"first","21":"instock","22":"taxable","23":"shipping-taxable","24":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product\/53674","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\/53643"}],"wp:attachment":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/media?parent=53674"}],"wp:term":[{"taxonomy":"soort","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/soort?post=53674"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_brand?post=53674"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_cat?post=53674"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_tag?post=53674"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
