This natural Fancy Color Diamond weighs 0.36 carat and is fashioned in a distinctive Square Cushion cut, combining a compact squared outline with softly rounded corners and a faceting arrangement that emphasises the stone’s warm natural colour.

The diamond is accompanied by ALGT Diamond Grading Report No. 11032913, which identifies the gemstone as a Natural Diamond and records its colour grade as NATURAL Fancy Yellowish Pinkish Brown.

Measuring approximately 3.71 × 3.59 × 2.91 mm, the stone has a compact face-up appearance with substantial depth. The extremely thick faceted girdle contributes to this depth and should be considered when comparing visible spread with total carat weight.

The colour is the defining visual characteristic of this specimen. Its combination of brown with yellowish and pinkish modifiers produces a complex warm tone with more nuance than a conventional brown diamond. The ALGT report specifically identifies the colour origin as natural, allowing the full laboratory colour description to be retained without simplification.

The diamond is graded I3 clarity, indicating prominent natural inclusions and internal structural features that are readily visible and significantly influence transparency, brilliance and overall optical refinement. These inclusions are part of the natural internal character of the gemstone and represent the principal limiting factor in its gemmological quality profile.

The polish is graded Good, supporting a generally well-finished facet surface, while symmetry is graded Fair, indicating some visible deviation from ideal facet alignment or proportion consistency.

The gemstone shows Faint fluorescence under ultraviolet illumination as recorded by the grading laboratory.

The diamond is supplied sealed and accompanied by its original ALGT grading certificate, preserving the direct connection between the gemstone and its laboratory documentation.

With its warm natural colour combination, compact Square Cushion form and independent laboratory certification, this 0.36 ct Fancy Color Diamond is an individual specimen suited to collectors, custom jewellery projects or buyers seeking a naturally coloured diamond with distinctive visual character.

Evaluation Notes

Lab-certified natural Diamond with natural fancy yellowish pinkish brown coloration and recorded clarity I3. The laboratory cutting, polish and symmetry observations were considered alongside colour presentation, internal character and overall optical appearance. The laboratory documentation records natural colour/origin without a colour-treatment indication.
This natural Fancy Color Diamond presents a **good overall gemmological quality profile**, with its strongest characteristic being the distinctive **Fancy Yellowish Pinkish Brown** natural colour. The **I3 clarity grade** reflects prominent inclusions and internal structural features that significantly reduce transparency, brilliance and overall optical refinement. The Square Cushion cut provides a compact face-up presentation, while the **Good polish** supports acceptable facet finish. **Fair symmetry** and the **extremely thick faceted girdle** limit proportion efficiency and reduce visible spread relative to carat weight. Despite these limitations, the natural colour origin, warm modifier combination and individual character support a solid overall **80/100** assessment.
