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> 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> Bergkristall Lucky Bottle aus China<\/p>","protected":false},"featured_media":53894,"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-54016","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-geluksflesjes","7":"pa_herkomst-china","8":"pa_soort-bergkristal","9":"pa_verkoopeenheid-per-10-stuks","10":"pa_vorm-geluksflesje","11":"pa_vorm-split","12":"desktop-align-center","13":"tablet-align-center","14":"mobile-align-center","15":"ast-product-gallery-layout-horizontal-slider","16":"ast-product-gallery-with-no-image","17":"ast-product-tabs-layout-horizontal","19":"first","20":"instock","21":"taxable","22":"shipping-taxable","23":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product\/54016","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\/53894"}],"wp:attachment":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/media?parent=54016"}],"wp:term":[{"taxonomy":"soort","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/soort?post=54016"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_brand?post=54016"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_cat?post=54016"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_tag?post=54016"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
