Natural Ruby · 0.4 ct · Pear · Mixed Cut · Heated · Madagascar

This natural Ruby weighs 0.40 carat and is fashioned in an elegant pear-shaped mixed cut, combining a classic tapered outline with a facet arrangement designed to enhance the gemstone’s red colour, brightness and overall face-up appearance.

Measuring approximately 5.3 × 3.8 × 2.6 mm, the gemstone presents balanced proportions suitable for individual jewellery design. Its transparent body allows the internal facet structure and natural colour to remain clearly visible despite the relatively compact carat weight.

The stone displays an attractive red body colour ranging from wine red to deep red, providing a rich and saturated visual character. The colour is assessed as very good, giving the gemstone strong presence despite its smaller size.

The clarity is comparable to approximately VS2, with fine natural inclusions and internal growth features visible under magnification but having only limited influence on the overall transparency and face-up appearance.

Ruby is the red gem variety of Corundum (Al₂O₃) and is valued for its combination of colour, hardness and durability. With a hardness of 9 on the Mohs scale, Ruby is particularly well suited to jewellery when properly cut and securely set.

The gemstone shows a Good to Very Good cut grade, with Good to Very Good symmetry and Good polish. These characteristics contribute to a balanced overall presentation, while the very good vitreous to subadamantine luster enhances surface brightness and visual refinement.

There are indications of heating, with no indications of any other treatment. The heat treatment is fully disclosed as part of the gemstone documentation and should be considered part of the stone’s gemmological profile.

This specimen is recorded as originating from Madagascar, an important source of gem-quality Ruby and other Corundum varieties.

With its rich red colour, transparent body and refined pear-shaped presentation, this 0.40 ct natural Ruby combines attractive colour with good clarity and balanced cutting quality. Its compact jewellery size and documented treatment status make it a versatile choice for a custom ring, pendant or other fine jewellery design.
