14.52 Ct. Amethyst from Brazil

This 14.52 carat fancy shaped purple amethyst from Brazil measures 21.90 x 15.70 x 10.30 mm, and has been executed in a precise step cut with an excellent polish. The cutter has emphasized broad, well defined step facets and a generous table plane to showcase the gemological properties of quartz, the result is a controlled display of broad flashes and color zones rather than the intense scintillation associated with brilliant cuts. Clarity is graded as very very slightly included at eye level, the stone reads visually clean for practical gem use, and the minimal internal features become compositional accents in the step faceting rather than distractions. Color intensity is medium intense, and the heat treatment applied is a standard, stable enhancement for Brazilian amethyst that optimizes the violet saturation without compromising crystalline integrity. The overall finishing shows tight facet junctions and symmetrical facet geometry, which together with the excellent polish maximizes transmitted light and surface luster, making the piece ideal for settings that emphasize table presence, such as statement rings and pendants.

When comparing reflective qualities to other gemstones in the same broad category, the optical behavior of this amethyst aligns with the inherent refractive and dispersive characteristics of quartz. Amethyst has a refractive index near 1.54 to 1.55 and low dispersion, which yields a vitreous luster and broad color flashes rather than pronounced fire, this step cut further emphasizes color rather than brilliance. Against other amethysts, this specimen compares favorably because the step cut and superior polish reduce visual windowing and enhance perceived color saturation, particularly useful for medium intense stones. Versus higher refractive index gems such as topaz and sapphire, which typically return more intense brilliance and greater spectral dispersion, this amethyst will show less fire and scintillation, but it offers a more uniform color field and elegant, architectural reflections that many connoisseurs prize for classic designs. Against other quartz varieties, such as citrine, the amethyst’s purple hue and step cut treatment produce deeper, more focused light returns. The Natural Gemstone Company presents this piece as a technically refined example of cut, clarity, and color management, suitable for buyers who appreciate the disciplined optical language of step faceting and the stable, consistent luster inherent to fine amethyst.
