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> Chalcedon-Geode aus Mexiko<\/p>","protected":false},"featured_media":67413,"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":[1348,1064],"product_tag":[1137],"class_list":{"0":"post-67428","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-unieke-producten","7":"product_cat-schijven","8":"product_tag-uniek","9":"pa_herkomst-mexico","10":"pa_soort-chalcedoon","11":"pa_verkoopeenheid-uniek","12":"pa_vorm-geode","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":"sold-individually","22":"taxable","23":"shipping-taxable","24":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product\/67428","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\/67413"}],"wp:attachment":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/media?parent=67428"}],"wp:term":[{"taxonomy":"soort","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/soort?post=67428"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_brand?post=67428"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_cat?post=67428"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_tag?post=67428"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
