Ruby is one of the most commercially misrepresented colored gemstones — heat-treated material is routinely sold without disclosure, and pink sapphires, red spinels, and low-quality material are sometimes sold as ruby entirely. A GIA report resolves the ambiguity: it confirms the material is natural corundum of ruby color, weight, dimensions, and origin, with treatment status stated explicitly as untreated.\u003c\/p\u003e\n\n\u003ch2\u003e\u003cspan role=\"text\"\u003e\u003cstrong\u003eKey Benefits of this Natural Unheated Ruby\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGIA-Documented Ruby\u003c\/strong\u003e\u003cbr\u003eIndependent confirmation of species, weight, dimensions, origin, and treatment status.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompletely Unheated\u003c\/strong\u003e\u003cbr\u003eNo indications of heating per GIA — a rare and highly sought-after distinction for ruby.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMadagascar Origin\u003c\/strong\u003e\u003cbr\u003eMadagascar is a significant modern source of fine natural ruby.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOval Cut Versatility\u003c\/strong\u003e\u003cbr\u003eThe most practical ruby shape for engagement rings and pendants.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable for Daily Wear\u003c\/strong\u003e\u003cbr\u003eCorundum at Mohs 9, second only to diamond.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003e\u003cspan role=\"text\"\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eItem #: CG8456\u003c\/li\u003e\n\u003cli\u003eCarat Weight: 1.65 Carats\u003c\/li\u003e\n\u003cli\u003eGem Type: Natural Ruby (Corundum)\u003c\/li\u003e\n\u003cli\u003eCut: Oval \/ Mixed Brilliant\u003c\/li\u003e\n\u003cli\u003eDimensions: 7.77 x 5.98 x 4.39mm\u003c\/li\u003e\n\u003cli\u003eOrigin: Madagascar\u003c\/li\u003e\n\u003cli\u003eTreatment: None — Unheated\u003c\/li\u003e\n\u003cli\u003eColor: Red \/ Intense\u003c\/li\u003e\n\u003cli\u003eClarity: Eye-clean — no visible inclusions under normal viewing\u003c\/li\u003e\n\u003cli\u003eTransparency: Transparent\u003c\/li\u003e\n\u003cli\u003eHardness: 9 on the Mohs scale\u003c\/li\u003e\n\u003cli\u003eCertification: GIA Report #2245032085\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003e\u003cspan role=\"text\"\u003e\u003cstrong\u003eCare of Your Madagascar Ruby\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eClean with lukewarm water and mild soap using a soft brush\u003c\/li\u003e\n\u003cli\u003eStore separately to avoid surface contact\u003c\/li\u003e\n\u003cli\u003eRemove before heavy physical activity\u003c\/li\u003e\n\u003cli\u003eAvoid ultrasonic or steam cleaners\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003e\u003cspan role=\"text\"\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGIA Report #2245032085\u003c\/li\u003e\n\u003cli\u003eGemstone packed in a gem sleeve\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003e\u003cspan role=\"text\"\u003e\u003cstrong\u003ePerfect Uses for this 1.65 ct Ruby\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eEngagement ring center stone\u003c\/li\u003e\n\u003cli\u003eStatement pendant or cocktail ring\u003c\/li\u003e\n\u003cli\u003eCollectors of GIA-documented unheated natural ruby\u003c\/li\u003e\n\u003cli\u003eJuly birthstone gift\u003c\/li\u003e\n\u003cli\u003eAnniversary or romantic milestone gift\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Crescent Gems","offers":[{"title":"Default Title","offer_id":43488589283395,"sku":"CG8456","price":11550.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8982\/8931\/files\/8456001.jpg?v=1783089221"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8982\/8931\/collections\/1112023001_36c3fdf3-7a0d-4f02-929c-401f89728ec3-1776781982.jpg?v=1781260410","url":"https:\/\/crescentgems.com\/en-gcc\/collections\/ruby-gemstones-loose-stones-gia-certification.oembed","provider":"Crescent Gems","version":"1.0","type":"link"}
