This natural 𝐒𝐩𝐞𝐬𝐬𝐚𝐫𝐭𝐢𝐭𝐞 𝐆𝐚𝐫𝐧𝐞𝐭 weighs 𝟏.𝟕𝟗 𝐜𝐭 and is fashioned in an attractive 𝐨𝐯𝐚𝐥 𝐦𝐢𝐱𝐞𝐝 𝐜𝐮𝐭, displaying a rich reddish-orange colour with lively orangy-red reflections and bright vitreous luster.

Measuring approximately 𝟕.𝟒 × 𝟔.𝟑 × 𝟒.𝟎 𝐦𝐦, the gemstone has a balanced oval outline with good face-up presence. Its saturated reddish-orange colour remains clearly visible under normal lighting conditions and does not require strong direct sunlight to reveal its warm orange-red character.

Spessartite is a manganese-rich member of the Garnet group and is particularly appreciated for its characteristic yellowish-orange, orange and reddish-orange colour range. In this specimen, the warm body colour is complemented by bright internal reflections and a 𝐯𝐢𝐭𝐫𝐞𝐨𝐮𝐬 𝐥𝐮𝐬𝐭𝐞𝐫 that enhances its overall visual appeal.

The gemstone is 𝐭𝐫𝐚𝐧𝐬𝐩𝐚𝐫𝐞𝐧𝐭 and displays a clarity profile comparable to 𝐈𝟏. Natural inclusions are therefore visible within the stone, but the material retains sufficient transparency to produce attractive internal reflections and a lively face-up presentation.

The cutting quality is assessed as 𝐟𝐚𝐢𝐫 𝐭𝐨 𝐠𝐨𝐨𝐝, supported by 𝐠𝐨𝐨𝐝 𝐬𝐲𝐦𝐦𝐞𝐭𝐫𝐲 and 𝐠𝐨𝐨𝐝 𝐩𝐨𝐥𝐢𝐬𝐡. The mixed-cut facet arrangement combines different facet geometries to balance colour retention and brilliance while maintaining the classic oval outline.

A 𝐭𝐢𝐧𝐲 𝐜𝐡𝐢𝐩 / 𝐬𝐜𝐫𝐚𝐭𝐜𝐡 is present and is not readily visible without magnification. It is documented as part of the gemstone’s current condition but does not strongly disturb the normal face-up appearance.

The recorded origin of this specimen is 𝐍𝐚𝐦𝐢𝐛𝐢𝐚.

There are 𝐧𝐨 𝐢𝐧𝐝𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬 𝐨𝐟 𝐡𝐞𝐚𝐭𝐢𝐧𝐠 and 𝐧𝐨 𝐢𝐧𝐝𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬 𝐨𝐟 𝐨𝐭𝐡𝐞𝐫 𝐭𝐫𝐞𝐚𝐭𝐦𝐞𝐧𝐭𝐬 for this gemstone.

With its 𝐫𝐢𝐜𝐡 𝐫𝐞𝐝𝐝𝐢𝐬𝐡-𝐨𝐫𝐚𝐧𝐠𝐞 𝐜𝐨𝐥𝐨𝐮𝐫, bright vitreous luster and attractive oval proportions, this 1.79 ct Namibian Spessartite Garnet offers a lively natural appearance with strong warm colour and good overall visual presence.

Evaluation Notes

This natural Spessartite Garnet presents a good overall quality profile, with its rich reddish-orange colour, transparent appearance and bright vitreous luster providing the main visual strengths.

The gemstone shows a clarity profile comparable to I1, with visible natural inclusions and internal structural variation that reduce internal cleanliness and slightly limit optical refinement. The fair to good cut, together with good symmetry and polish, produces an attractive overall face-up presentation, although the light return is less balanced than in a more precisely cut specimen.

A tiny chip / scratch is present and is mainly visible under magnification. Its visual impact is limited in normal viewing, but it remains a documented condition factor in the overall assessment.

The combination of saturated colour, good transparency, luster and acceptable cutting quality, balanced against the included clarity and minor surface condition issue, supports an overall 70/100 assessment.

Natural CharacteristicsThe Spessartite Garnet displays a transparent internal structure with a rich reddish-orange body colour and lively orangy-red reflections. Natural inclusions are visible within the stone, consistent with a clarity profile comparable to I1, while sufficient transparency remains to produce attractive internal brilliance. Fine internal features, small included crystals and subtle structural variations contribute to the gemstone’s natural character without completely obscuring its bright face-up appearance. Localised darker areas may occur through the interaction of body colour, depth and facet-related extinction. A tiny chip / scratch is present and is primarily visible under magnification. This forms part of the gemstone’s documented condition but has limited visibility during normal face-up observation. The combination of saturated reddish-orange colour, transparent material, natural inclusions and bright vitreous luster gives this Spessartite Garnet a distinctive and lively appearance.
