Onyx<\/a> ist eine gestreifte Variet\u00e4t des Chalcedons, einer mikrokristallinen Form des Quarzes. Er ist bekannt f\u00fcr seine parallelen Streifen in kontrastierenden Farben, in der Regel schwarz und wei\u00df. Im Edelsteinhandel wird der Name h\u00e4ufig f\u00fcr schwarz gef\u00e4rbten Chalcedon verwendet, obwohl sich der echte Onyx durch seine Schichtstruktur auszeichnet. Onyx wird seit Jahrhunderten f\u00fcr Kameen, Schmuck und dekorative Gegenst\u00e4nde verwendet.<\/p>\n Gro\u00dfe Onyxvorkommen gibt es in Indien, Brasilien, Uruguay, den Vereinigten Staaten und Mexiko. Das Mineral bildet sich in Hohlr\u00e4umen von Vulkangestein, wo Kiesels\u00e4urel\u00f6sungen langsam in Schichten auskristallisieren. Onyx geh\u00f6rt chemisch gesehen zu SiO\u2082 und hat eine H\u00e4rte von 6,5 bis 7 auf der Mohs-Skala.<\/p>\n Quellen: <\/strong> Onyx-Trommelsteine aus S\u00fcdafrika<\/p>","protected":false},"featured_media":62074,"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":[1044],"product_tag":[],"class_list":{"0":"post-62071","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-trommelstenen","7":"pa_herkomst-zuid-afrika","8":"pa_maat-m-l-trommelstenen","9":"pa_soort-onyx","10":"pa_verkoopeenheid-per-100-gr","11":"pa_vorm-getrommeld","12":"desktop-align-center","13":"tablet-align-center","14":"mobile-align-center","15":"ast-product-gallery-layout-horizontal-slider","16":"ast-product-tabs-layout-horizontal","18":"first","19":"instock","20":"taxable","21":"shipping-taxable","22":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product\/62071","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\/62074"}],"wp:attachment":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/media?parent=62071"}],"wp:term":[{"taxonomy":"soort","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/soort?post=62071"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_brand?post=62071"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_cat?post=62071"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_tag?post=62071"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
