Amethyst from Brazil is widely respected for its consistency and availability in larger sizes, and this example shows the variety’s classic appeal in a clean, structured fancy octagonal outline. The cutting quality is good, with proportions that support a pleasing spread and dependable brilliance, while the loupe-clean clarity allows the color to remain the focal point. Faint color zoning is present, which is consistent with natural amethyst and does not detract from the overall eye appeal. With no enhancement noted, the stone retains a straightforward and desirable gemological profile. Its substantial size and elongated outline make it especially suitable as a statement ring stone, a pendant centerpiece, or a custom design requiring a vivid yet elegant purple quartz of notable presence.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eGemstone Specification\u003c\/b\u003e\u003c\/p\u003e\n\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003ctd\u003eShort description\u003c\/td\u003e\n\u003ctd\u003eLoose 37.35 ct Fancy Octagon Cut Natural Amethyst Gemstone, Brazil\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eCountry of origin\u003c\/td\u003e\n\u003ctd\u003eBrazil\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eGemstone type\u003c\/td\u003e\n\u003ctd\u003eAmethyst\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eCarat weight\u003c\/td\u003e\n\u003ctd\u003e37.35\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eDimensions (mm)\u003c\/td\u003e\n\u003ctd\u003e25.03 x 14.33 x 14.33\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eHue (GIA)\u003c\/td\u003e\n\u003ctd\u003e4\/3 violetish Purple\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eTone (GIA)\u003c\/td\u003e\n\u003ctd\u003emedium light (4)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eSaturation (GIA)\u003c\/td\u003e\n\u003ctd\u003every slightly brownish (3)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eCut style or shape\u003c\/td\u003e\n\u003ctd\u003eFancy Octagon Cut\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eCutting quality\u003c\/td\u003e\n\u003ctd\u003eGood\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eClarity Type\u003c\/td\u003e\n\u003ctd\u003eType I\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eClarity\u003c\/td\u003e\n\u003ctd\u003eLoupe Clean\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eTreatment\u003c\/td\u003e\n\u003ctd\u003eNot enhanced\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eInclusions\u003c\/td\u003e\n\u003ctd\u003efaint colour zoning\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eBrilliance grade\u003c\/td\u003e\n\u003ctd\u003eGood\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e1000274\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003cp\u003e\u003cb\u003eCredentials\u003c\/b\u003e\u003cbr\u003e\nCertified Professional Gemologist - Internation Gem Society\u003cbr\u003e\nGIA Certificate - Colored Stones 2023\u003cbr\u003e\nGIA Colored Gemstone Identification Lab Course, 2024\u003cbr\u003e\nGIA Colored Gemstone Grading Lab Course, 2025\u003cbr\u003e\nProfessional Geologist and optical mineralogy expert\u003c\/p\u003e","brand":"Frontier Gemstones","offers":[{"title":"Default Title","offer_id":53105316233536,"sku":"1000274","price":100.0,"currency_code":"GBP","in_stock":true}],"url":"https:\/\/frontiergemstones.com\/products\/loose-37-35-ct-fancy-octagon-cut-natural-amethyst-gemstone-brazil","provider":"Frontier Gemstones","version":"1.0","type":"link"}
