1.27 Ct. Purple Amethyst from Brazil

This transparent 1.27 carat oval purple amethyst measures 8.39 by 7.20 by 3.83 millimeters, yielding a depth of about 49 percent, a proportion that supports balanced light return without excess windowing or deep loss of brilliance. The stone is faceted in a mixed brilliant cut, combining a modified brilliant crown with a faceted pavilion, which enhances both broad facet flashes and pinpoint scintillation. Clarity is graded very very slightly included evaluated at eye level, indicating the gem is effectively eye clean with only minute internal features visible under magnification. Color presents at medium intensity, a balanced purple that retains saturation without appearing overly dark, and the polish is excellent with crisp facet junctions and smooth facet planes. No enhancement has been applied, and the origin is Brazil, a source known for consistent crystal quality and natural color distribution. The cutter has prioritized symmetry and crown pavilion alignment to maximize constancy of face up color and to minimize potential color zoning in the oval outline.

In reflection characteristics this amethyst exhibits the expected vitreous luster and the refractive behavior typical of quartz, with a refractive index around 1.544 to 1.553 and low birefringence, which together produce a steady, even brilliance and restrained fire. Compared with other stones in its category, such as citrine and smoky quartz which share similar refractive optics, this Brazilian amethyst shows comparable light performance, with its medium purple saturation enhancing perceived depth and contrast. Against higher refractive index gems commonly used in the same jewelry categories, such as corundum and spinel, the amethyst returns slightly less intense brilliance and markedly lower dispersion, so its visual appeal is driven more by color saturation and facet pattern than by fire. The mixed brilliant cut applied here increases scintillation relative to step cuts often used for quartz, producing more dynamic light play on movement, while the excellent polish preserves crisp reflective transitions. For designers and discerning buyers seeking a naturally colored, eye clean purple gem with reliable wearability and controlled sparkle, this piece from The Natural Gemstone Company offers a technically refined option that balances cut geometry, clarity, and true untreated origin.
