Serpentine<\/a> is a group of minerals formed by the hydrothermal conversion of olivine and pyroxene in ultramafic rocks. Its colour ranges from light green to dark green, sometimes with a marble-like pattern. Serpentine has a waxy to silky luster and a smooth surface, making it popular for decorative use and sculpture.<\/p>\n Major deposits of serpentine include China, Italy, Afghanistan, the US and South Africa. The chemical composition varies, but common forms are antigorite, lizardite and chrysotile. The general formula is (Mg,Fe)\u2083Si\u2082O\u2085(OH)\u2084. Serpentine has a hardness of 2.5 to 5.5 on the Mohs scale, depending on the variety.<\/p>\n A popular variety is \"New Jade\", a trade name for a light green form of serpentine often used as an alternative to jade in jewellery and decorative objects. So, despite the name, it is not real jade, but serpentine with a jade-like appearance.<\/p>\n Sources: <\/strong> \n These faceted, ball or beaded bracelets are strung on a sturdy, double elastic, making them suitable for different wrist sizes. Our bracelets range in bead diameter from 4 mm to 10 mm, with the wrist circumference varying slightly by size. The smaller sizes have a wrist circumference of about \u00b1 160 mm, increasing to \u00b1 180 mm for the larger ones. For children's bracelets, the wrist circumference is the smallest in our range, which is \u00b1 12 to 13 cm.\n<\/p>\n \n We also offer split bracelets, where the split used ranges from 5 to 10 mm. These bracelets are also strung on sturdy, double elastic, with a circumference of approximately 16 cm to a maximum of 18 cm. Please note that there may sometimes be a different type between the pieces of split used. Our split bracelets are sold per 10 pieces in most cases, but there are exceptions.\n<\/p>\n \n Please note that we do not always have every size of every variety in our range.<\/p>\n<\/p>","protected":false},"excerpt":{"rendered":" Lantian Jade - Serpentine Ball Bracelet in 6 mm<\/p>","protected":false},"featured_media":56029,"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":[1843],"product_tag":[],"class_list":{"0":"post-56081","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-6-mm-kogelarmband","7":"pa_herkomst-china","8":"pa_maat-6-mm","9":"pa_soort-serpentijn","10":"pa_verkoopeenheid-per-stuk","11":"pa_vorm-armband","12":"pa_vorm-kogelarmband","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\/en\/wp-json\/wp\/v2\/product\/56081","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\/56029"}],"wp:attachment":[{"href":"https:\/\/www.ruschmineralen.nl\/en\/wp-json\/wp\/v2\/media?parent=56081"}],"wp:term":[{"taxonomy":"soort","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/en\/wp-json\/wp\/v2\/soort?post=56081"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/en\/wp-json\/wp\/v2\/product_brand?post=56081"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/en\/wp-json\/wp\/v2\/product_cat?post=56081"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/en\/wp-json\/wp\/v2\/product_tag?post=56081"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
