Natural Amethyst weighing 0.369 ct and measuring approximately 5.8 × 3.9 × 2.6 mm, fashioned in a classic oval mixed cut that combines a refined outline with lively internal reflections.

The gemstone displays a rich violet to deep purple body colour with vivid magenta-violet flashes appearing as the stone moves under light. Its colour quality ranges from very good to excellent, with attractive saturation and sufficient brightness to retain a lively appearance despite the deeper purple tone.

The mixed faceting is very well executed, producing good brilliance and an appealing balance between darker contrast areas and brighter violet reflections. Cut, symmetry and polish are all very good, giving the stone a neat, well-proportioned appearance with clean facet junctions and a pleasing oval outline.

Clarity is assessed as VS, with only minor natural internal characteristics visible under magnification and no major inclusions apparent from the supplied photographs. The overall transparency remains strong, supporting both colour depth and light return.

A refined natural Amethyst with attractive purple saturation, very good craftsmanship and a balanced optical appearance, suitable for a delicate ring, pendant, earrings or a small collector gemstone.

Evaluation Notes

This 0.369 ct natural Amethyst presents a refined combination of rich violet colour, good transparency and well-executed faceting. The gemstone shows a saturated violet to deep purple body colour with vivid magenta-violet flashes, giving it strong visual presence despite its relatively small carat weight.

Colour quality is assessed as very good to excellent, with attractive saturation and sufficient brightness to prevent the stone from appearing overly dark. Minor natural colour zoning is visible under close inspection but does not materially detract from the face-up appearance.
Clarity is consistent with the assigned VS grade. Small natural internal characteristics, including pinpoint inclusions and subtle veils, are visible under magnification but remain unobtrusive and do not significantly interfere with brilliance or transparency.
The oval mixed cut is very well executed, with a balanced outline, good facet arrangement and very good symmetry. Polish is likewise very good, supporting clean surface reflections and a refined overall finish. Light return is attractive, with lively violet flashes and good contrast across the crown, although the optical performance is not quite at the exceptional level seen in precision-cut or custom-cut material.
Overall, this is a high-quality natural Amethyst combining strong colour, good clarity and very good craftsmanship in a compact, jewellery-suitable size.

Natural CharacteristicsThe gemstone shows minor natural internal characteristics consistent with natural Amethyst, including small pinpoint inclusions and subtle internal veils visible under magnification. Very slight colour zoning can be observed, with deeper violet concentrations alternating with lighter purple areas across the stone. The material remains transparent overall, and the inclusions do not significantly interrupt the stone’s brilliance or face-up appearance. No major fractures or strongly eye-visible inclusions are apparent from the supplied photographs. These subtle internal and colour-related features support the natural character of the gemstone while remaining compatible with the assigned VS clarity grade.
