Originating from Brazil, it shows a medium light tone with very slightly brownish saturation and a medium pinkish purple hue, giving the color a softly romantic character rather than an overly vivid look. The excellent cutting quality is reflected in the balanced symmetry and the stone’s good brilliance, which helps bring out the broad flashes of purple light across the step facets.\n\nAs a Type I gemstone, amethyst is typically expected to be relatively clean, and this example is eye-clean to the unaided eye. Under 10x magnification, minor magnetite grains are noted, a natural inclusion feature consistent with the species and not unexpected in a large quartz gem. The stone has not been enhanced, which will appeal to buyers seeking natural color and straightforward gemological provenance.\n\nIts substantial size and elegant octagonal form make it a strong candidate for a statement ring, a bold pendant, or a bespoke centerpiece in a fine jewelry design.\n\n\u003cb\u003eGemstone Specification\u003c\/b\u003e\n\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003ctd\u003eShort description\u003c\/td\u003e\n\u003ctd\u003eLoose 37.45 ct Stepped 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\u003e37.45 ct\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e21.0 x 11.3 x 7.0 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eHue (GIA)\u003c\/td\u003e\n\u003ctd\u003emedium pinkish 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\u003eStepped Octagon Cut\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eCutting quality\u003c\/td\u003e\n\u003ctd\u003eExcellent\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eClarity\u003c\/td\u003e\n\u003ctd\u003eEye 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\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e1000273\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\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","brand":"Frontier Gemstones","offers":[{"title":"Default Title","offer_id":53105316200768,"sku":"1000273","price":100.0,"currency_code":"GBP","in_stock":true}],"url":"https:\/\/frontiergemstones.com\/products\/loose-37-45-ct-stepped-octagon-cut-natural-amethyst-gemstone-brazil","provider":"Frontier Gemstones","version":"1.0","type":"link"}
