0.99 Ct. Amethyst from Ceylon (Sri Lanka)

This transparent 0.99 carat round purple amethyst measures 6.54 x 6.49 x 4.62 mm, presented in a mixed brilliant cut that combines pavilion and crown facet configurations to balance depth and scintillation. The stone is evaluated as eye clean at typical viewing distance, showing no visible inclusions that would interrupt light return. Color intensity is described as intense, yielding a vivid violet that is evenly distributed across the table and crown. The surface finish is of excellent polish, producing a smooth and reflective face up appearance. There has been no enhancement to this stone, and its documented origin is Ceylon Sri Lanka, which contributes to its geologic provenance and market character.

Under natural daylight, the mixed brilliant facet arrangement returns a lively display of brilliance and fire, with strong white flashes and an underlying saturated violet body color. Direct sunlight enhances contrast and can bring forward warmer red violet tones within the intense color, while diffuse northern daylight emphasizes the cooler blue violet spectrum, giving a slightly different but consistent impression when compared side by side. In warm incandescent illumination the amethyst tends to read richer and more wine like as red violet components become more pronounced. Under cool fluorescent lighting, and under common white LED sources, the stone maintains good sparkle, with the mixed facets producing noticeable scintillation during movement. Amethyst commonly exhibits subtle pleochroism, and this specimen will show slight shifts between bluish violet and reddish violet as it is rotated beneath the light, a quality that complements its gemological integrity and eye clean clarity.

For mounting and wear, the gem’s nearly one carat weight and round outline provide dependable face up presence in a variety of jewelry types, with white metal settings enhancing perceived brilliance and yellow gold subtly warming the apparent hue. The combination of excellent polish and absence of enhancements means the stone will respond well to expert cutting and secure settings that maximize light entry, such as open collet or low bezel styles. The Natural Gemstone Company offers this parcel as a natural, untreated amethyst from Ceylon Sri Lanka, and recommends routine gentle cleaning with mild detergent and a soft brush to preserve polish and optical performance.
