Howlite<\/a> ist ein Kalziumborsilikat, das in der Regel wei\u00df mit grauen bis schwarzen Adern ist, was ihm ein marmor\u00e4hnliches Aussehen verleiht. Aufgrund seiner por\u00f6sen Struktur wird Howlit oft eingef\u00e4rbt, um T\u00fcrkis zu \u00e4hneln. Das Mineral wurde 1868 in Nova Scotia, Kanada, entdeckt und ist nach dem kanadischen Chemiker Henry How benannt.<\/p>\n Howlit kommt haupts\u00e4chlich in Kanada, China und den Vereinigten Staaten, insbesondere in Kalifornien, vor. Er bildet sich in borreichen Evaporitumgebungen und ist oft in kleinen Ablagerungen in Sedimentgestein zu finden. Seine chemische Formel lautet Ca\u2082B\u2085SiO\u2089(OH)\u2085 und seine H\u00e4rte betr\u00e4gt 3,5 bis 6,5 auf der Mohs-Skala.<\/p>\n Quellen: <\/strong> Donut-Edelstein-Anh\u00e4nger sind flache, runde Anh\u00e4nger mit einer zentralen Bohrung von etwa 5-6 mm. Es gibt sie in verschiedenen Edelsteinsorten und Gr\u00f6\u00dfen von etwa 2,5 bis 5 cm, wobei 3 cm bei uns am h\u00e4ufigsten vorkommen. Dank ihrer Form lassen sie sich gut an einer Kordel oder Kette tragen.<\/p>\n<\/p>","protected":false},"excerpt":{"rendered":" Howlite Donut-Anh\u00e4nger, 3 cm gro\u00df<\/p>","protected":false},"featured_media":55887,"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":[1050],"product_tag":[],"class_list":{"0":"post-55863","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-donut-hangers","7":"pa_herkomst-china","8":"pa_maat-3-cm","9":"pa_soort-howliet","10":"pa_verkoopeenheid-per-stuk","11":"pa_vorm-donut","12":"pa_vorm-hanger","13":"desktop-align-center","14":"tablet-align-center","15":"mobile-align-center","16":"ast-product-gallery-layout-horizontal-slider","17":"ast-product-gallery-with-no-image","18":"ast-product-tabs-layout-horizontal","20":"first","21":"instock","22":"taxable","23":"shipping-taxable","24":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product\/55863","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\/55887"}],"wp:attachment":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/media?parent=55863"}],"wp:term":[{"taxonomy":"soort","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/soort?post=55863"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_brand?post=55863"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_cat?post=55863"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_tag?post=55863"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
