Carefully polished to reveal its dense structure and subtle tonal variation, the specimen ranges from dark forest green through to near jet black, shaped by natural mineral composition and iron-rich inclusions.\u003c\/p\u003e\n\u003cp data-start=\"519\" data-end=\"856\"\u003eBlack jade is composed primarily of two closely related mineral types: sodium aluminium silicate (jadeite) and calcium magnesium silicate (nephrite). While both are commonly referred to as jade, they differ in density, crystal structure, hardness, and formation processes, giving each specimen distinct physical character and appearance.\u003c\/p\u003e\n\u003cp data-start=\"858\" data-end=\"1130\"\u003eThe characteristic dark colouring of black jade originates from iron oxide inclusions within the stone. While the base material is often deep green, these natural inclusions darken the material over time, producing the rich near-black tones seen in high-quality specimens.\u003c\/p\u003e\n\u003cp data-start=\"1380\" data-end=\"1549\"\u003eSelected for the Australian Museum Shop, this specimen is suited to collectors seeking authentic, natural mineral examples with strong geological and aesthetic presence.\u003c\/p\u003e\n\u003cp data-start=\"1380\" data-end=\"1549\"\u003e\u003cstrong\u003eDimensions: \u003c\/strong\u003eangular in shape, this 12mm slice is 180 x60mm at widest and tallest points\u003c\/p\u003e\n\u003cp data-start=\"1380\" data-end=\"1549\"\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 250g\u003c\/p\u003e","brand":"Australian Museum Shop","offers":[{"title":"Default Title","offer_id":54074424787228,"sku":"MISLICE-12","price":239.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0293\/3394\/6416\/files\/Polished-black-Jade-specimen.jpg?v=1777945567","url":"https:\/\/shop.australian.museum\/products\/black-jade-specimen-west-australian-museum-quality-collector-piece","provider":"Australian Museum Shop","version":"1.0","type":"link"}
