This individually documented natural Spessartite Garnet is presented by Natural Gems Belgium with its specimen-specific identification, measurements and recorded characteristics. Weighing 1.17 carats, this transparent gemstone displays an attractive deep orangy-red colour, combining the warm orange influence characteristic of Spessartite with a stronger reddish body tone.

The gemstone has been fashioned into an elegant oval shape with a mixed cut, measuring approximately 7.30 × 5.70 × 2.82 mm. Its cutting quality is assessed within the Good to Very Good range, providing a balanced presentation and effective light return while preserving the individual character of the natural material.

Spessartite belongs to the broader garnet mineral group and is particularly valued for its warm colour range, which can extend from yellowish orange and vivid orange through to deeper reddish-orange and orangy-red tones. Its characteristic colour is associated primarily with manganese within the garnet crystal structure.

This specimen is transparent, allowing light to travel effectively through the stone and enhancing both its colour presence and brilliance. As with natural garnet material, subtle inclusions, internal growth features or minor surface characteristics may occur and form part of the gemstone’s individual geological identity.

No indications of treatment have been recorded for this gemstone. It is therefore presented in its naturally documented state, without evidence of enhancement.

This natural Spessartite Garnet presents a strong overall quality profile, combining attractive deep orangy-red colour, good transparency and a well-balanced oval mixed cut.

The gemstone’s colour presence, cutting quality and overall visual appeal support an excellent overall assessment, while the internal characteristics remain the principal limiting factor.
