Chalcedon<\/a> ist eine mikrokristalline Quarzsorte, die in einer breiten Farbpalette vorkommt, wobei blau, grau und wei\u00df die bekanntesten sind. Der Stein hat einen wachsartigen Glanz und ist oft durchscheinend. Aufgrund seiner feinen Struktur wird Chalcedon h\u00e4ufig f\u00fcr Schmuck und dekorative Gegenst\u00e4nde verwendet.<\/p>\n Chalcedon bildet sich in Hohlr\u00e4umen von Vulkangestein, wo er sich Schicht f\u00fcr Schicht aus kiesels\u00e4urereichen L\u00f6sungen ablagert. Er kommt weltweit vor, mit bedeutenden Vorkommen u. a. in der T\u00fcrkei, Namibia, Brasilien, den Vereinigten Staaten und Indien. Seine chemische Zusammensetzung ist SiO\u2082 und seine H\u00e4rte liegt zwischen 6,5 und 7 auf der Mohs-Skala.<\/p>\n Quellen: <\/strong> Apophyllit<\/a> ist eine Gruppe von Schichtsilikatmineralen, die h\u00e4ufig in klaren, prismenf\u00f6rmigen Kristallen mit glasartigem bis perlmuttartigem Glanz vorkommen. Die Farbe reicht von farblos und wei\u00df bis gr\u00fcn oder rosa, je nach Spuren anderer Elemente. Aufgrund seiner charakteristischen Kristallform und Transparenz ist Apophyllit bei Sammlern sehr beliebt und wird h\u00e4ufig in Kombination mit Zeolithen gefunden.<\/p>\n Gro\u00dfe Vorkommen gibt es in Indien, Brasilien, Deutschland, Island und den Vereinigten Staaten. Apophyllit bildet sich in der Regel in den Hohlr\u00e4umen von basaltischen Laven und anderen vulkanischen Gesteinen durch hydrothermale Prozesse. Seine allgemeine Formel lautet KCa\u2084Si\u2088O\u2082\u2080(F,OH)-8H\u2082O, und seine H\u00e4rte liegt zwischen 4,5 und 5 auf der Mohs-Skala.<\/p>\n Quellen: <\/strong> Chalcedon mit Apophyllit aus Indien<\/p>","protected":false},"featured_media":56265,"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":[1348,1073],"product_tag":[1137],"class_list":{"0":"post-56256","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-unieke-producten","7":"product_cat-gekristalliseerd","8":"product_tag-uniek","9":"pa_herkomst-india","10":"pa_soort-apofylliet","11":"pa_soort-chalcedoon","12":"pa_verkoopeenheid-uniek","13":"pa_vorm-gekristalliseerd","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":"sold-individually","23":"taxable","24":"shipping-taxable","25":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product\/56256","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\/56265"}],"wp:attachment":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/media?parent=56256"}],"wp:term":[{"taxonomy":"soort","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/soort?post=56256"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_brand?post=56256"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_cat?post=56256"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_tag?post=56256"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
