Tourmaline quartz<\/a> is a variety of quartz that contains black needle-like inclusions of tourmaline (usually sch\u00f6rl). The contrast between the clear or milky quartz and the darker tourmaline needles gives the stone a distinctive and unique appearance. This makes each piece different and popular in both jewellery and collectibles.<\/p>\n Major deposits of tourmaline quartz include Brazil, Madagascar, Pakistan and the United States. The mineral is formed when quartz and tourmaline crystallise simultaneously in pegmatites or hydrothermal veins. The chemical formula of the quartz is SiO\u2082, combined with inclusions of tourmaline, and its hardness is 7 on the Mohs scale.<\/p>\n Sources: <\/strong> The stone cut into double-cylinder is fixed in a silver- or gold-coloured holder with eye. The double-inder has a length of about 3.2 cm, measured without the eye. These pendants are available in various stone types and are supplied individually. Due to the use of natural stone, colour, markings and finish may vary slightly from one pendant to another.<\/p>\n<\/p>","protected":false},"excerpt":{"rendered":" Tourmaline quartz Double Butterfly Pendant from China<\/p>","protected":false},"featured_media":61330,"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":[3388],"product_tag":[],"class_list":{"0":"post-61354","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-dubbeleinder-hangers","7":"pa_herkomst-china","8":"pa_maat-32-cm","9":"pa_soort-toermalijnkwarts","10":"pa_verkoopeenheid-per-stuk","11":"pa_vorm-dubbeleinder","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-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\/61354","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\/61330"}],"wp:attachment":[{"href":"https:\/\/www.ruschmineralen.nl\/en\/wp-json\/wp\/v2\/media?parent=61354"}],"wp:term":[{"taxonomy":"soort","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/en\/wp-json\/wp\/v2\/soort?post=61354"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/en\/wp-json\/wp\/v2\/product_brand?post=61354"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/en\/wp-json\/wp\/v2\/product_cat?post=61354"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/en\/wp-json\/wp\/v2\/product_tag?post=61354"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
