This natural bluish Green Tourmaline weighs 1.18 carats and is fashioned in an elegant pear-shaped mixed cut, combining a vibrant bluish green body colour with good transparency and a balanced overall presentation.

Measuring approximately 8.2 × 6.0 × 4.0 mm, the gemstone presents an attractive elongated pear outline suitable for an individual jewellery design. Its lighter green colour allows good transmission of light through the transparent material and gives the stone a fresh, lively face-up appearance.

The gemstone displays a bluish green body colour, with subtle tonal variation possible depending on viewing direction and illumination. Tourmaline is naturally pleochroic, so slight differences in colour intensity may be observed from different crystallographic orientations.

The stone is transparent but strongly included, with a clarity comparable to approximately I3. Numerous natural inclusions, internal growth features and healed fissures are visible and have a significant influence on internal cleanliness. Despite this inclusion level, the gemstone continues to transmit light and maintains an attractive light green colour.

The pear-shaped mixed cut is assessed as Good, with Good symmetry and Fair polish. These finishing qualities support a balanced outline, clean surface reflections and an attractive vitreous luster.

A small chip is present on the curved side below the girdle. This characteristic is clearly documented and should be considered during handling and jewellery setting. Its position below the girdle limits its influence on the normal face-up appearance of the gemstone.

There are no indications of heating and no indications of any other treatment. The stone is therefore presented with its naturally observed colour and internal characteristics without documented enhancement.

The gemstone is documented by Natural Gems Belgium, providing documented identification and quality evaluation.

With its vibrant bluish green colour, transparent body and elegant pear-shaped presentation, this 1.18 ct natural Green Tourmaline retains attractive visual character despite its strongly included clarity profile. The combination of natural colour, good cutting quality and untreated condition makes it an individual gemstone for jewellery or collection purposes.

Evaluation Notes

This natural bluish-green Tourmaline presents a **good overall gemmological quality profile**, with its attractive bluish-green colour and good transparency forming the principal visual strengths. The gemstone has an **I3 clarity profile**, with numerous natural inclusions, internal growth features and healed fissures that significantly reduce internal cleanliness and optical performance.

The pear-shaped mixed cut is assessed as **Good**, supported by good symmetry and good polish, which help preserve a balanced outline and attractive vitreous luster. A small chip on the curved side below the girdle is an additional structural limitation and should be considered during setting, although its position limits its impact on normal face-up appearance.

Overall, the combination of appealing natural colour, transparent body and good cutting quality is offset by the strong inclusion level and minor chip, supporting a **74/100 assessment**.
