{"product_id":"1-73-ct-radiant-white-sapphire-colorless","title":"1.73 ct Natural Unheated White Sapphire – Radiant Cut","description":"\u003cp\u003eA natural 1.73 carat white sapphire in a radiant cut, colorless and untreated. White sapphire is natural corundum that formed without the trace elements that produce color — the same mineral species as blue, yellow, or pink sapphire but entirely without chromophores. The radiant cut at 1.73 carats produces a stone with strong face-up presence and a modern rectangular silhouette — a format that delivers both architectural clarity and brilliant light return in colorless material.\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=\"\/ja-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\"Untreated colorless sapphire above 1.5 carats is genuinely scarce — most white sapphire on the market has been heat treated to remove residual color, so a natural, untreated 1.73 ct stone with eye-clean clarity is not something you'll find in every parcel.\"\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 it under bright, direct light.\u003c\/strong\u003e Radiant cuts perform best under strong lighting, so assess brilliance in conditions similar to where you'll wear it.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConsider the setting for an elongated silhouette.\u003c\/strong\u003e At 8.42 x 5.27 mm, this radiant suits an east-west or classic four-prong solitaire setting; confirm your setting accommodates the rectangular outline.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfirm treatment status directly when comparison shopping.\u003c\/strong\u003e Untreated stones are the minority of white sapphire on the market, and the term \"natural\" alone does not guarantee untreated — ask for documentation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeigh availability at this size and treatment status.\u003c\/strong\u003e Untreated colorless sapphire at this size and clarity is a narrower slice of the market than heat-treated white sapphire, which affects both price and availability, as described above.\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=\"\/ja-cn\/blogs\/information-pages-complete-guide\/white-sapphire-buyers-guide\"\u003eWhite Sapphire Buyer's Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/ja-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=\"\/ja-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=\"\/ja-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=\"\/ja-cn\/blogs\/information-pages-complete-guide\/sapphire-vs-moissanite-vs-lab-diamond\"\u003eSapphire vs. Moissanite vs. Lab Diamond\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/ja-cn\/blogs\/information-pages-complete-guide\/sapphire-buying-guide\"\u003eSapphire Buying Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Crescent Gems","offers":[{"title":"Default Title","offer_id":42665948053571,"sku":"CG7994","price":8200.14,"currency_code":"CNY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8982\/8931\/files\/1112023001_b031465a-385b-4683-a01a-c92270d4946a.jpg?v=1778308011","url":"https:\/\/crescentgems.com\/ja-cn\/products\/1-73-ct-radiant-white-sapphire-colorless","provider":"Crescent Gems","version":"1.0","type":"link"}
