Karneol<\/a> ist eine rote bis orangefarbene Variet\u00e4t des Chalcedons und erh\u00e4lt seine Farbe durch Eisenoxide. Das Mineral wird seit dem Altertum f\u00fcr Schmuck, Siegelsteine und Amulette verwendet. Die Farbe reicht von hellem Orange bis zu tiefem Rot, abh\u00e4ngig von der Eisenkonzentration und der Art der Erhitzung w\u00e4hrend oder nach der Entstehung.<\/p>\n Gro\u00dfe Vorkommen gibt es in Indien, Brasilien, Uruguay und Madagaskar. Karneol bildet sich in vulkanischem Gestein und Sedimentablagerungen. Seine chemische Formel lautet SiO\u2082 und er hat eine H\u00e4rte von 6,5 bis 7 auf der Mohs-Skala.<\/p>\n Beliebte Variet\u00e4ten sind der geb\u00e4nderte Karneol und erhitzte Formen, die besonders intensiv gef\u00e4rbt sind, aber von der Struktur her demselben Mineraltyp angeh\u00f6ren.<\/p>\n Quellen: <\/strong> Selenit<\/a> ist eine klare bis durchscheinende Variante des Minerals Gips (CaSO\u2084-2H\u2082O). Er ist bekannt f\u00fcr seinen glasigen bis perligen Glanz und seine oft faserige Struktur. Eine h\u00e4ufige Form ist der Selenit, der einen Seidenglanz hat und in langen, faserigen Kristallen vorkommt. Trotz seines Namens hat Selenit nichts mit dem Element Selen zu tun; der Name leitet sich vom griechischen Wort f\u00fcr Mond ab, wegen seines weichen Glanzes.<\/p>\n Selenit bildet sich in sediment\u00e4ren Umgebungen w\u00e4hrend der Verdunstung von Meerwasser und ist in L\u00e4ndern wie Mexiko, Marokko, den USA und Australien zu finden. Es ist ein weiches Mineral mit einer H\u00e4rte von 2 auf der Mohs-Skala, so dass es sich leicht von Hand bearbeiten l\u00e4sst. Fast der gesamte auf dem niederl\u00e4ndischen Markt verkaufte Selenit ist Satinspat; Selenit ist jedoch ein vom Markt akzeptierter Handelsname.<\/p>\n Quellen: <\/strong> Karneol geb\u00e4nderte Gl\u00fccksflasche aus China<\/p>","protected":false},"featured_media":53902,"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":[3250],"product_tag":[],"class_list":{"0":"post-54023","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-geluksflesjes","7":"pa_herkomst-china","8":"pa_soort-carneool","9":"pa_soort-carneool-geband","10":"pa_verkoopeenheid-per-10-stuks","11":"pa_vorm-geluksflesje","12":"pa_vorm-split","13":"desktop-align-center","14":"tablet-align-center","15":"mobile-align-center","16":"ast-product-gallery-layout-horizontal-slider","17":"ast-product-gallery-with-no-image","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\/54023","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\/53902"}],"wp:attachment":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/media?parent=54023"}],"wp:term":[{"taxonomy":"soort","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/soort?post=54023"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_brand?post=54023"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_cat?post=54023"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_tag?post=54023"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
