Ametrine is a naturally occurring variety of quartz that displays both amethyst purple and citrine yellow within the same crystal, the result of differing oxidation states of iron in different zones of the stone during its formation.\u003c\/p\u003e\u003cp\u003eIn geode form, this dual colouration creates a breathtaking interior — a cavity lined with crystals that transition between rich violet and warm golden yellow, sometimes within a single point. Each ametrine geode is entirely unique, as the distribution of colour is determined by the precise conditions present during millions of years of crystal growth.\u003c\/p\u003e\u003cp\u003eAmetrine is found in only a handful of locations worldwide, making this a genuinely rare collector's piece as well as a visually spectacular one.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMineral:\u003c\/strong\u003e Ametrine (Amethyst-Citrine Quartz)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 400g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm:\u003c\/strong\u003e Natural crystal geode\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILBO LAGS Jewellery and Gems and Fossils","offers":[{"title":"Default Title","offer_id":53022461591872,"sku":"53022461591872","price":280.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0993\/4238\/5472\/files\/17866987528682945596167456803682.jpg?v=1786698763","url":"https:\/\/milbolags.myshopify.com\/products\/natural-ametrine-crystal-geode-400g","provider":"MILBO LAGS Jewellery and Gems and Fossils","version":"1.0","type":"link"}
