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> Handsteine sind unsere gr\u00f6\u00dften, getrommelten und glatt polierten (Edel-)Steine, die oft sehr gut in der Hand liegen, was den Namen sofort erkl\u00e4rt. Getrommelt wird diese Gr\u00f6\u00dfe auch als Handstein oder Jumbo-Stein bezeichnet. Oft werden diese Steine nach dem Trommeln extra poliert oder geschliffen, um ein sch\u00f6nes Endergebnis zu erzielen. Trotz dieser Konsistenz handelt es sich um ein Naturprodukt, so dass es immer zu Abweichungen in Form, Farbe und Muster kommen kann. Dies kann von einer Steinart zur anderen variieren.<\/p>\n In der Regel haben die Handsteine eine Gr\u00f6\u00dfe zwischen 4 \u00d7 3 \u00d7 2 cm und 6 \u00d7 5 \u00d7 3 cm. Fast alle unsere Handsteine stammen aus Madagaskar, wo sie sorgf\u00e4ltig ausgew\u00e4hlt und verarbeitet werden. Die Produktfotos geben einen guten Eindruck von dem, was Sie erwartet. Handsteine werden pro 100 gr (1x) verkauft, bei einer Mindestbestellmenge von 500 gr (5x).<\/p>\n<\/p>","protected":false},"excerpt":{"rendered":" Strass-Handsteine aus Madagaskar<\/p>","protected":false},"featured_media":52292,"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":[1042],"product_tag":[],"class_list":{"0":"post-52298","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-handstenen","7":"pa_herkomst-madagaskar","8":"pa_soort-bergkristal","9":"pa_soort-kwarts","10":"pa_verkoopeenheid-per-100-gr","11":"pa_vorm-getrommeld","12":"pa_vorm-handsteen","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":"taxable","22":"shipping-taxable","23":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product\/52298","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\/52292"}],"wp:attachment":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/media?parent=52298"}],"wp:term":[{"taxonomy":"soort","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/soort?post=52298"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_brand?post=52298"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_cat?post=52298"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_tag?post=52298"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
