{"product_id":"1-21-ct-trillion-shape-blue-sapphire","title":"1.21 ct Natural Heated Blue Sapphire – Trillion (Trilliant) Cut","description":"\u003cp\u003eA natural 1.21 carat blue sapphire in a trillion (trilliant) cut, heat treated. Trillion-cut blue sapphire is one of the less common format combinations in the market — most blue sapphires are cut oval or cushion for weight efficiency, so a true trillion represents a deliberate shape choice. The three-sided geometric outline of the trillion produces a face-up footprint significantly larger than the carat weight suggests, and the equal-sided triangular form has a bold, architectural character that stands apart from conventional engagement ring shapes.\u003c\/p\u003e\u003cdiv style=\"border: 2px solid #5b2c6f; border-radius: 10px; padding: 20px 24px; margin: 28px 0; background-color: #f9f5fc;\"\u003e\n\u003ch2 style=\"margin-top: 0; margin-bottom: 12px; color: #4a235a;\"\u003eExpert Opinion\u003c\/h2\u003e\n\u003cp style=\"font-weight: 600; margin-bottom: 6px;\"\u003e\u003ca href=\"\/en-cn\/pages\/ahmed-shareek-about-the-owner\" style=\"color: #4a235a; text-decoration: underline;\"\u003eAhmed Shareek\u003c\/a\u003e's Assessment\u003c\/p\u003e\n\u003cp style=\"font-style: italic; margin-bottom: 0;\"\u003e\"This 1.21 ct trillion-cut blue sapphire combines a dark, richly saturated Ceylon blue with a step-cut triangular silhouette — a shape combination genuinely uncommon in the blue sapphire market, where most material is cut oval or cushion.\"\u003c\/p\u003e\n\u003c\/div\u003e\u003ch2\u003eGood to Know\u003c\/h2\u003e\u003cp\u003eA few practical points to weigh before purchasing this specific stone:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eView the stone in daylight and under warm indoor light —\u003c\/strong\u003e dark saturated blues can read almost inky under low light, so confirm the tone works in the lighting where you'll wear it most.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAt 7.05 x 6.30mm with three pointed corners,\u003c\/strong\u003e this stone requires a setting with V-prong or protected corner tips — standard for trillion cuts but worth confirming with your jeweler before mounting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhen comparison-shopping,\u003c\/strong\u003e confirm heat treatment disclosure and lab source in writing, and ask whether any comparable stone offered is a true trillion or a modified triangular cut.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeigh the scarcity noted above,\u003c\/strong\u003e since a true trillion-cut center stone in a dark, saturated blue is harder to source than an oval or cushion of the same color and weight.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse the Try Before You Buy option\u003c\/strong\u003e if you would like to see the stone in hand before finalizing the purchase.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003e\u003cspan role=\"text\"\u003e\u003cstrong\u003eLearn More About This Gemstone\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/en-cn\/blogs\/information-pages-complete-guide\/blue-sapphire-buyers-guide\"\u003eBlue Sapphire Buyer's Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/en-cn\/blogs\/information-pages-complete-guide\/what-is-an-unheated-sapphire\"\u003eUnheated Sapphire Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/en-cn\/blogs\/information-pages-complete-guide\/what-is-a-gia-sapphire-report-and-how-do-you-read-one\"\u003eGIA Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/en-cn\/blogs\/information-pages-complete-guide\/how-to-commission-custom-sapphire-ring\"\u003eCustom Ring Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/en-cn\/blogs\/information-pages-complete-guide\/sapphire-buying-guide\"\u003eSapphire Buying Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/en-cn\/blogs\/information-pages-complete-guide\/how-to-care-for-a-sapphire-engagement-ring-cleaning-storage-and-what-to-avoid\"\u003eHow to Care for a Sapphire Engagement Ring\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Crescent Gems","offers":[{"title":"Default Title","offer_id":42665947758659,"sku":"CG8228","price":9479.86,"currency_code":"CNY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8982\/8931\/files\/stone_CG8228_image-1.jpg?v=1778351201","url":"https:\/\/crescentgems.com\/en-cn\/products\/1-21-ct-trillion-shape-blue-sapphire","provider":"Crescent Gems","version":"1.0","type":"link"}
