Natural Amethyst weighing 0.236 ct and measuring approximately 4.0 × 3.9 × 2.6 mm, fashioned in a classic round brilliant cut.

The gemstone displays a medium violet-purple body colour with lively lilac to brighter violet flashes appearing as the stone moves under light. The colour remains attractive and well distributed overall, with a pleasant balance between deeper purple areas and brighter reflective zones.

Clarity is assessed as SI. Natural internal characteristics are visible under magnification and from certain viewing angles, including small inclusions and fine internal features that are consistent with natural Amethyst. Despite these characteristics, the stone remains transparent overall and retains an appealing level of brilliance.

The round brilliant faceting provides good light return for its compact size, creating distinct flashes across the crown and a pleasing face-up appearance. The outline is close to round, with balanced proportions and an attractive visual presentation.

Its 4 mm format makes this natural Amethyst particularly suitable for delicate rings, earrings, pendants or accent settings where a compact violet gemstone is desired.

Evaluation Notes

This 0.236 ct natural Amethyst shows an attractive medium violet-purple colour with lighter lilac and brighter violet flashes under direct illumination. The colour is well distributed overall, although slightly lighter and less saturated than higher-grade material.
Clarity is assessed as SI. Several natural internal characteristics are visible under magnification, including pinpoint inclusions, fine internal veils and localized reflective features. These inclusions are noticeable from certain viewing angles but do not prevent the gemstone from maintaining good transparency and an attractive face-up appearance.
The round brilliant cut provides good light return for its compact size, with a balanced near-round outline and a generally pleasing facet arrangement. Symmetry appears good to very good, while the polish is consistent with a commercially well-finished natural gemstone.
Optical performance is good, with lively violet flashes across portions of the crown, although some areas remain less active depending on the viewing angle. The overall appearance is attractive and well suited to delicate jewellery.

Natural CharacteristicsThe gemstone shows natural internal characteristics consistent with Amethyst, including small pinpoint inclusions, fine internal veils and localized inclusion concentrations visible under magnification. A few small reflective internal features can be observed from certain viewing angles, consistent with the assigned SI clarity grade. Subtle colour zoning is also present, with areas of medium violet-purple alternating with lighter lilac-purple sections. The stone remains transparent overall, and the inclusions do not completely disrupt its face-up brilliance. No major structural fractures or severe surface-reaching features. These minor inclusions, internal growth-related features and natural colour variations contribute to the individual character of the gemstone and are compatible with natural quartz formation.
