Bergkristall<\/a> ist die farblose, transparente Variante des Quarzes und besteht aus reinem Siliziumdioxid. Er kristallisiert im trigonalen Kristallsystem und bildet oft gut ausgebildete sechsseitige Prismen mit einer spitzen Spitze. Aufgrund seiner Klarheit und seines Glasglanzes ist der Bergkristall eine der bekanntesten und am h\u00e4ufigsten verwendeten Quarzsorten.<\/p>\n Das Mineral kommt weltweit vor, mit bedeutenden Vorkommen u. a. in Brasilien, Madagaskar, der Schweiz und den Vereinigten Staaten. Der Bergkristall kommt in hydrothermalen Adern, Pegmatiten und metamorphen Gesteinen vor. Seine chemische Formel lautet SiO\u2082 und seine H\u00e4rte betr\u00e4gt 7 auf der Mohs-Skala. Bekannte Quarzarten wie Rosenquarz, Amethyst und Rauchquarz unterscheiden sich vom Bergkristall durch ihre farbgebenden Einschl\u00fcsse oder Strahlungseinfl\u00fcsse.<\/p>\n Quellen: <\/strong> Strasspunkte AA aus Brasilien.<\/p>","protected":false},"featured_media":56350,"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":[2992],"product_tag":[],"class_list":{"0":"post-56348","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-punten-per-gewicht","7":"pa_herkomst-brazilie","8":"pa_soort-bergkristal","9":"pa_verkoopeenheid-per-100-gr","10":"pa_vorm-punt","11":"desktop-align-center","12":"tablet-align-center","13":"mobile-align-center","14":"ast-product-gallery-layout-horizontal-slider","15":"ast-product-gallery-with-no-image","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\/56348","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\/56350"}],"wp:attachment":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/media?parent=56348"}],"wp:term":[{"taxonomy":"soort","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/soort?post=56348"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_brand?post=56348"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_cat?post=56348"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_tag?post=56348"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
