5.83 Ct. Purple Amethyst from Ceylon (Sri Lanka)

This transparent 5.83 carat oval amethyst presents measured dimensions of 13.48 x 10.63 x 6.98 mm, a mixed brilliant cut, and an eye level clarity grade of very slightly included. The stone displays intense purple color intensity with an excellent polish, and no enhancement noted. Origin is Ceylon Sri Lanka, and the combination of size and cut produces a strong face up presence with well defined facet symmetry. The mixed brilliant design balances a scintillating crown with a faceted pavilion that returns light efficiently, and the excellent polish ensures crisp facet junctions and a smooth girdle finish. At eye level the inclusions are minimal and do not interrupt the flow of light across the table, so the stone reads clean and vivid in typical viewing conditions. The Natural Gemstone Company presents this amethyst in a professional selection of natural gems, with documentation of origin and enhancement status available on request.

Under natural daylight the amethyst exhibits a true violet hue with cool blue undertones and high saturation, the mixed brilliant facets producing lively flashes of light and a stable color that reads evenly across the table. Under warm incandescent illumination the stone shifts to a richer, warmer purple with subtle red overtones, and the pavilion facets create more contrast and deeper flashes due to longer wavelength light. Under modern LED lighting the appearance is balanced, preserving both the cool and warm aspects of the color, while fluorescent light can soften the tone slightly, offering a paler but still intense presentation. In lower light and candlelight the strong polish and facet alignment yield crisp pinpoint scintillation, permitting small bright flashes against a deeper purple body color. Because the gem is transparent and untreated, its response to different lighting is natural and predictable, and the stone will perform reliably in a variety of mounting styles. When set in open prong settings the amethyst benefits from increased light entry and maximum brilliance, while bezel settings emphasize color saturation and protect the gem without significantly diminishing its visual appeal.
