5.13 Ct. Purple Amethyst from Brazil

This exceptional specimen from The Natural Gemstone Company is a transparent, round shape amethyst weighing 5.13 carat, with precise dimensions of 11.69 x 11.64 x 7.37 mm, executed in a faceted mixed brilliant cut, and finished to an excellent polish. The mixed brilliant design combines a brilliant style crown with a modified pavilion facet arrangement to marry strong light return with controlled depth of color, delivering both scintillation and even tone across the face of the stone. Clarity is graded as very very slightly included, evaluated at eye level, which indicates inclusions are minimal and do not disrupt visual performance or durability. This gem is untreated, certified as no enhancement, and sourced from Brazil, where careful material selection yields consistent crystal quality and saturated color. The round outline is symmetrical with well centered table proportions, the girdle presentation supports precision settings, and the overall cutting approach optimizes weight retention while preserving a lively optical profile.

The color of this amethyst is the defining attribute, a rich bold purple with intense color intensity, presenting a saturated violet core with slightly bluish undertones that convey depth without appearing black in darker lighting. The hue saturation is uniform, with minimal zoning, allowing the stone to read as a single powerful color plane when viewed face up, and to reveal layered color dynamics as the stone moves. The mixed brilliant cut enhances these dynamics by breaking light into crisp flashes that animate the purple, enabling a balance between apparent saturation and surface brightness. For the discerning buyer who values symbolism as well as gemological excellence, this rich bold color functions as a clear emblem of personal power and distinction, projecting confidence in a way that is both visually striking and technically sound. The excellent polish ensures strong facet junctions and smooth planes, maximizing contrast and edge definition to support the impression of strength and refinement.

From a practical and design perspective this amethyst is well suited for prominent settings where its color and cut can be showcased, including solitaire rings, halo designs, and pendant applications. With a hardness of 7 on the Mohs scale, and a specific gravity close to that of quartz, this gem combines everyday wearability with a reassuring resistance to abrasion, though prudent care is recommended to avoid hard knocks and prolonged exposure to strong heat or direct sunlight which can gradually affect color over extended periods. The refractive index range typical for amethyst yields predictable light performance, and the mixed brilliant faceting has been calibrated to leverage that refractivity for optimal return. At The Natural Gemstone Company we present this stone as a natural, unenhanced example of Brazilian amethyst, and we stand behind its origin and clarity assessment, offering guidance on secure prong or bezel settings that preserve crown facets and maximize face up color. For clients seeking a piece that communicates individuality and authority through gemological integrity and masterful cutting, this 5.13 carat round amethyst is an ideal candidate, and our team is available to discuss mounting options, matching pairs, or certification details to ensure the selected setting complements the stone without compromising its visual potency.
