This exceptional natural Citrine weighs an impressive 52.403 carats and is fashioned in a large cushion-shaped custom cut measuring approximately 27.6 × 20.9 × 14.8 mm. Its extraordinary carat weight gives the gemstone commanding visual presence, while the carefully designed concave facet structure creates a sophisticated architectural appearance and strong internal light movement.

The colour is best described as light golden yellow to champagne-gold, with warmer honey-gold and occasional amber reflections appearing through the deeper and concave-cut sections of the stone. Despite its substantial size, the body colour remains remarkably open and luminous rather than overly dark, allowing light to travel effectively through the gemstone.

Clarity is comparable to VVS, with only very minor natural internal characteristics visible under magnification. The exceptionally high transparency is particularly notable for a Citrine of this size and allows the complex custom cutting to remain clearly visible throughout the stone.

The custom cushion cut is graded as very good and makes excellent use of the exceptional volume of the rough material. Broad central facets are combined with elongated and concave-cut sections that generate strong directional reflections, long golden flashes and pronounced optical depth. The faceting creates an almost architectural light pattern, with alternating areas of calm transparency and concentrated brilliance.

The substantial depth of the gemstone contributes to its strong three-dimensional appearance, while the cushion outline remains well balanced for such an unusually large stone. The polished surfaces support a bright vitreous lustre and reinforce the clean, high-clarity presentation.

At over 52 carats, this Citrine belongs to an exceptional size category and is best suited to collector use, high-end bespoke jewellery or a major statement design where its scale and sophisticated custom cutting 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 large natural Citrine combining remarkable 52.403 ct weight, VVS-equivalent clarity, luminous champagne-gold colour and a highly distinctive custom concave cut with strong optical depth and visual impact.

Evaluation Notes

An excellent natural Citrine distinguished by its exceptional 52.403 ct weight, very high transparency and sophisticated custom concave cutting. The gemstone displays a light golden-yellow to champagne-gold body colour, complemented by warmer honey-gold and amber reflections that become more pronounced through the deeper and concave-cut areas.

Clarity is comparable to VVS, with only very minor natural internal characteristics visible under magnification. Considering the extraordinary size of the gemstone, the level of transparency is particularly impressive and allows the complex internal facet architecture to remain clearly visible throughout the stone.
The custom cushion cut is very good and produces strong directional reflections, elongated golden flashes and pronounced three-dimensional depth. The concave facets add substantial optical interest and create a dynamic contrast between broad transparent areas and more concentrated zones of brilliance. Symmetry appears very good for a gemstone of this scale, while the polished surfaces support a clean vitreous lustre and strong overall presentation.
The 52.403 ct carat weight is exceptional and forms one of the strongest quality factors of the stone. Despite its large dimensions, the gemstone retains good visual balance and does not appear excessively dark or closed, which is particularly favourable for a Citrine of this size.
Overall, the combination of exceptional carat weight, VVS-equivalent clarity, refined custom cutting, strong transparency and distinctive optical depth supports an excellent overall evaluation, with the lighter colour saturation preventing the stone from entering the very highest scoring range.

Natural CharacteristicsVery minor natural internal characteristics are visible under magnification, including isolated pinpoints, faint growth-related features and occasional subtle reflective inclusions. These remain extremely discreet relative to the exceptional size of the gemstone and are consistent with a VVS-equivalent clarity assessment. Overall transparency is very high, and the natural characteristics do not materially interfere with the champagne-gold colour, vitreous lustre or the strong optical effects produced by the large custom concave cut.
