{"product_id":"1-42-ct-round-white-sapphire-colorless","title":"1.42 ct Natural Unheated White Sapphire – Round Cut","description":"\u003cp\u003eA natural 1.42 carat white sapphire in a round cut, colorless and untreated. White sapphire is corundum without chromophore trace elements — the same mineral as blue, pink, or yellow sapphire, but entirely colorless. At Mohs 9, it is the hardest colorless gemstone alternative to diamond. At 1.42 carats in a round cut, this stone has the size and format that most directly replaces a diamond in a standard solitaire setting — without the diamond price point.\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=\"\/de-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 1.42 ct round white sapphire is untreated and loupe-clean — genuinely colorless corundum with no coating, filling, or heat enhancement, cut in the round brilliant format that most directly substitutes for a diamond in a solitaire setting.\"\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 in both daylight and warm indoor light —\u003c\/strong\u003e colorless stones can pick up faint warmth from surrounding metal, so check the stone under the lighting you'll wear it in most.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAt 7.40 x 7.34mm,\u003c\/strong\u003e this stone sits comfortably in a standard 4- or 6-prong solitaire head sized for a diamond of similar face-up diameter, without custom fabrication.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhen comparison-shopping,\u003c\/strong\u003e confirm treatment status in writing — many white sapphires on the market are diffusion-treated or coated, which this stone is not.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeigh the scarcity noted above,\u003c\/strong\u003e since genuinely untreated, loupe-clean white sapphire above 1 carat is harder to source than the broader white sapphire category.\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=\"\/de-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=\"\/de-cn\/blogs\/information-pages-complete-guide\/is-a-round-sapphire-good-for-an-engagement-ring-cut-color-and-what-to-know-before-you-buy\"\u003eIs a Round Sapphire Good for an Engagement Ring?\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/de-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=\"\/de-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=\"\/de-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=\"\/de-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":42665947856963,"sku":"CG8037","price":4907.82,"currency_code":"CNY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8982\/8931\/files\/1112023001_558daef4-afe9-42d0-bcb3-0c1269b2bc8b.jpg?v=1778307990","url":"https:\/\/crescentgems.com\/de-cn\/products\/1-42-ct-round-white-sapphire-colorless","provider":"Crescent Gems","version":"1.0","type":"link"}
