At 0.43 carats in a round cut, this is a small stone with the most practical format for its scale — round calibrated sapphires fit the widest range of standard earring, pendant, and accent settings without custom fabrication. Natural and unheated, the yellow color is exactly as the earth formed it, which is a meaningful distinction even at sub-half-carat weight.\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=\"\/zh-hans-de\/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\"Most yellow sapphire on the market under half a carat has been heat-treated to intensify color, so this 0.43 ct round at 4.60 x 4.60 x 2.83 mm stood out to me for showing bright, even natural yellow with no thermal history, confirmed on AGCL Report #M262740.\"\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 natural daylight.\u003c\/strong\u003e Yellow sapphire's saturation can appear warmer under incandescent light and cooler under daylight or LED — check both before deciding.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfirm your setting's seat size against 4.60 mm.\u003c\/strong\u003e This round calibrates close to a standard 4.5–4.75mm seat — verify your specific mounting before ordering.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRequest the lab report directly, not a summary.\u003c\/strong\u003e AGCL Report #M262740 documents this stone's treatment status independently — ask for it when comparison-shopping.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIf buying for Jyotish use, confirm unheated status explicitly.\u003c\/strong\u003e Traditional use of Pukhraj typically requires unheated natural sapphire; this stone's AGCL report supports that requirement.\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=\"\/zh-hans-de\/blogs\/information-pages-complete-guide\/yellow-sapphire-buyers-guide\"\u003eYellow Sapphire Buyer's Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/zh-hans-de\/blogs\/information-pages-complete-guide\/what-is-an-unheated-sapphire\"\u003eUnheated Sapphire Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/zh-hans-de\/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=\"\/zh-hans-de\/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=\"\/zh-hans-de\/blogs\/information-pages-complete-guide\/buying-sapphires-for-jyotish-vedic-astrology\"\u003eBuying Sapphires for Jyotish (Vedic Astrology)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/zh-hans-de\/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":43009078657091,"sku":"CG8389","price":98.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8982\/8931\/files\/1112023001_5ccaaa2c-2a79-4ac7-ab67-3c848520d920.jpg?v=1778308056","url":"https:\/\/crescentgems.com\/zh-hans-de\/products\/0-43-ct-round-unheated-yellow-sapphire","provider":"Crescent Gems","version":"1.0","type":"link"}
