The geometric facet arrangement produces structured reflections across the face of the stone, giving it the architectural character associated with this style of step cutting without making unsupported claims about clarity.\u003c\/p\u003e\n\u003cp\u003eAt 1.64 carats and 6.04 × 5.66 × 5.01 mm, the sapphire presents a compact near-square face-up proportion with substantial depth. Its defined geometry and vivid royal blue colour make it particularly suitable as the centre stone of an engagement ring, three-stone composition, refined pendant, or bespoke fine-jewellery design.\u003c\/p\u003e","brand":"SARATTI","offers":[{"title":"Default Title","offer_id":43519571820605,"sku":"1275121","price":10650.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0066\/5416\/5061\/files\/1.64ct_Unheated_Natural_Madagascar_Royal_Blue_Sapphire_Asscher_main_view_SARATTI.webp?v=1787751391","url":"https:\/\/saratti.com\/products\/1-64-carats-unheated-natural-madagascar-royal-blue-sapphire-asscher","provider":"SARATTI","version":"1.0","type":"link"}
