Grandidierite is a rare magnesium aluminum borosilicate mineral prized for its distinctive blue-green to greenish blue coloration. Its unusual mineral composition and limited occurrence make it particularly interesting to gemstone collectors.

Madagascar is the best-known source of gem-quality grandidierite, producing specimens in attractive bluish green hues. The gemstone's distinctive color makes it an uncommon alternative to more familiar blue and green gemstones.

This specimen is unheated, retaining its naturally occurring coloration without enhancement. Its opaque clarity emphasizes the gemstone's solid color and natural appearance rather than transparency or internal brilliance.

At 4.91 carats and measuring 12.0 x 9.7 x 7.0 mm, this grandidierite offers attractive proportions for a custom pendant, distinctive jewelry design, or mineral collection.

Grandidierite has a Mohs hardness of approximately 7 to 7.5, providing reasonable resistance to scratching with appropriate care. Protective settings and careful handling are recommended.

This individual Madagascan grandidierite combines rare mineral identity, attractive bluish green coloration, and natural unheated character in a distinctive collector gemstone.
