This natural Citrine weighs 8.625 carats and is fashioned in a distinctive oval custom cut measuring approximately 16.0 × 11.8 × 8.5 mm. Its sophisticated concave facet architecture gives the gemstone a highly individual appearance, combining broad areas of saturated colour with concentrated flashes of light and strong internal contrast.

The colour is best described as deep cognac-gold to rich brownish orange, complemented by vivid reddish-orange and warm amber reflections. As the stone is rotated, the darker body colour opens into brighter orange flashes through the pavilion, creating considerable visual depth and a dynamic appearance. The strong saturation and warm tonal range are among the principal qualities of this Citrine.

Clarity is comparable to VS, with natural internal characteristics visible under magnification while overall transparency remains high. These minor characteristics do not significantly interfere with the gemstone’s colour or optical presentation.

The custom cut is excellent and represents one of the strongest features of this stone. Carefully executed concave facets create additional internal reflections and produce a more dramatic light pattern than a conventional oval mixed cut. The very good symmetry maintains a balanced overall outline, while the very good polish supports clean facet reflections and a strong vitreous lustre.

At 8.625 carats, the gemstone has substantial visual presence while remaining highly practical for bespoke jewellery. Its elongated oval proportions, saturated colour and unusual concave cutting make it particularly suitable for a statement ring or pendant where the optical effect can be fully appreciated.

No indications of heating have been observed. The gemstone is therefore presented as natural Citrine with no indications of heat treatment.

Overall, this is an exceptional visually expressive Citrine combining excellent custom cutting, rich cognac-orange colour, VS-equivalent clarity and strong optical performance within a substantial but wearable 8.625 ct size.

Evaluation Notes

An exceptional natural Citrine combining rich cognac-gold to brownish-orange colour with vivid amber and reddish-orange flashes, substantial 8.625 ct weight and a highly distinctive custom concave cut. The colour is strongly saturated and shows excellent depth, while the concave facet architecture creates pronounced internal reflections, lively contrast and a dynamic optical appearance that changes noticeably with movement. Clarity is comparable to VS, with fine natural characteristics visible under magnification but without significant impact on transparency or brilliance. Cut quality is excellent, with the concave faceting executed to a high standard and producing strong light return and visual character. Symmetry is very good, the oval outline is well balanced, and the very good polish supports crisp reflections and a strong vitreous lustre. The combination of saturated colour, refined cutting, substantial carat weight and high optical performance supports an exceptional overall evaluation.

Natural CharacteristicsFine natural internal inclusions and growth-related features are visible under magnification, including small pinpoints, subtle internal veils and occasional tiny reflective characteristics. These natural features remain relatively discreet and are consistent with the gemstone’s VS-equivalent clarity. Overall transparency remains high, and the inclusions do not materially disturb the rich cognac-orange colour, vitreous lustre or the strong optical performance created by the concave custom cut.
