{"product_id":"1-37-ct-oval-royal-blue-sapphire-ceylon","title":"1.37 ct Natural Heated Blue Sapphire – Oval Cut | Sri Lanka (Ceylon)","description":"\u003cp\u003eA natural 1.37 carat royal blue Ceylon sapphire in an oval cut, heat treated. Royal blue is the most prized hue position in blue sapphire — a medium-dark, strongly saturated pure blue with no significant gray, green, or violet modifier. It is the color most associated with museum-quality Kashmir and Burmese sapphires, and at the finest end of Ceylon production, the same royal blue character is achievable. The oval cut at 1.37 carats places this stone squarely in the commercial center stone size range for engagement rings and pendants.\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-hk\/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\"The hue on this 1.37 ct oval is what I'd call true royal blue — medium-dark, fully saturated, with no gray or violet creeping in — and Ceylon origin combined with eye-clean clarity at this size is a genuinely strong combination for the price point.\"\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 more than one light source.\u003c\/strong\u003e Royal blue sapphire can shift subtly toward navy under warm indoor light, so check it in the lighting you'll wear it in most.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConsider the setting head size.\u003c\/strong\u003e At 7.42 x 5.52 mm, this oval sits comfortably in a classic four- or six-prong solitaire without needing an oversized setting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAsk for the saturation and tone grade when comparison shopping.\u003c\/strong\u003e \"Royal blue\" is used loosely in the trade, and many stones marketed that way are actually mid-tone or gray-modified blue.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeigh availability at this hue and size.\u003c\/strong\u003e Ceylon-origin royal blue sapphire above 1 carat with eye-clean clarity is a narrower slice of the market than lighter or grayer blue stones of the same size.\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-hk\/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=\"\/de-hk\/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-hk\/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-hk\/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-hk\/blogs\/information-pages-complete-guide\/oval-sapphire-guide\"\u003eOval Sapphire Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/de-hk\/blogs\/information-pages-complete-guide\/ceylon-sapphire-complete-guide\"\u003eCeylon Sapphire Complete Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/de-hk\/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":42665948151875,"sku":"CG1000","price":8758.81,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8982\/8931\/files\/stone_CG1000_image-1.jpg?v=1778307997","url":"https:\/\/crescentgems.com\/de-hk\/products\/1-37-ct-oval-royal-blue-sapphire-ceylon","provider":"Crescent Gems","version":"1.0","type":"link"}
