Its opaque character emphasizes the gemstone's body color rather than internal transparency, while the graceful pear-shaped outline provides an attractive teardrop silhouette.

Grandidierite is a rare magnesium-aluminum borosilicate mineral first discovered in Madagascar in 1902. It was named in honor of French naturalist and explorer Alfred Grandidier, who conducted extensive studies of Madagascar's natural history. The mineral is particularly admired for its characteristic blue-green coloration, which is primarily associated with iron within its crystal structure.

Although grandidierite is considered a rare mineral species, its gemological value varies considerably according to transparency, color, size, and overall quality. Transparent, facetable specimens are exceptionally uncommon, while opaque examples offer a different collectible appeal through their distinctive coloration and unusual mineral identity.

This gemstone is unheated, retaining its naturally occurring coloration without heat enhancement. Its opaque clarity contributes to its individual appearance, emphasizing the natural color and substantial form of the gemstone rather than transparency or internal brilliance.

At 11.41 carats with dimensions of 18.3 x 13.3 x 9.8 mm, this grandidierite offers impressive visual presence. Its substantial size and elegant pear shape make it particularly well suited for a custom statement pendant, where its greenish blue coloration and distinctive silhouette can be prominently displayed. It also makes an interesting addition to a collection of uncommon gemstone species.

Madagascar holds a special place in the history of grandidierite as the location of its original discovery. The island remains an important source of this unusual mineral and is internationally recognized for its remarkable diversity of colored gemstones. With a hardness of approximately 7 to 7.5 on the Mohs scale, grandidierite offers reasonable scratch resistance when handled with care.

An impressive earth-mined greenish blue grandidierite offering natural color, elegant pear-cut styling, and substantial size, together with the distinctive character of a rare gemstone species.
