Turquoise<\/a> is an opaque, blue to blue-green phosphate mineral that has been valued as a gemstone for thousands of years. The colour results from the presence of copper, while iron sometimes causes a greener hue. Turquoise often occurs with dark matrix lines of surrounding rock, giving it a distinctive appearance. The stone was named after the Turkish trade routes through which it was introduced to Europe.<\/p>\n Major deposits of turquoise are Iran, the United States (especially Arizona and Nevada), China and Egypt. The mineral forms in dry, desert areas as a secondary mineral in the oxidation zones of copper deposits. Its chemical formula is CuAl\u2086(PO\u2084)\u2084(OH)\u2088-4H\u2082O. Turquoise has a hardness of 5 to 6 on the Mohs scale.<\/p>\n Sources: <\/strong> Selenite<\/a> is a clear to translucent variety of the mineral gypsum (CaSO\u2084-2H\u2082O). It is known for its glassy to pearly luster and often fibrous structure. A common form is selenite, which has a silky luster and occurs in long, fibrous crystals. Despite its name, selenite has nothing to do with the element selenium; the name is derived from the Greek word for moon, because of its soft luster.<\/p>\n Selenite forms in sedimentary environments during the evaporation of seawater and is found in countries such as Mexico, Morocco, the US and Australia. It is a soft mineral with a hardness of 2 on the Mohs scale, making it easy to work by hand. Almost all selenite sold on the Dutch market is satin spar; however, selenite is a market-accepted sales name.<\/p>\n Sources: <\/strong> Turquoise Lucky Bottle from China<\/p>","protected":false},"featured_media":53885,"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-54006","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-geluksflesjes","7":"pa_herkomst-china","8":"pa_soort-turkoois","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\/en\/wp-json\/wp\/v2\/product\/54006","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.ruschmineralen.nl\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.ruschmineralen.nl\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/en\/wp-json\/wp\/v2\/media\/53885"}],"wp:attachment":[{"href":"https:\/\/www.ruschmineralen.nl\/en\/wp-json\/wp\/v2\/media?parent=54006"}],"wp:term":[{"taxonomy":"soort","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/en\/wp-json\/wp\/v2\/soort?post=54006"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/en\/wp-json\/wp\/v2\/product_brand?post=54006"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/en\/wp-json\/wp\/v2\/product_cat?post=54006"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/en\/wp-json\/wp\/v2\/product_tag?post=54006"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
