Carved blue stone figurine, likely dyed or treated sodalite

Sodalite, Na₈(Al₆Si₆O₂₄)Cl₂ (tentative identification)

AI-generated identification · may be incorrect

Opaque, mottled blue with pale veining and a polished surface; sodalite has Mohs hardness 5.5–6, vitreous to greasy luster, and a cubic crystal structure. The carving and image alone do not allow a secure mineral identification; similar pieces may be dyed stone.

Physical properties

Opaque, mottled blue with pale veining and a polished surface; sodalite has Mohs hardness 5.5–6, vitreous to greasy luster, and a cubic crystal structure. The carving and image alone do not allow a secure mineral identification; similar pieces may be dyed stone.

Formation & geological history

If sodalite, it formed in silica-poor, sodium-rich igneous rocks such as nepheline syenite; such deposits occur in several geological ages. The figurine was subsequently carved and polished.

Uses & applications

Carved as a decorative or souvenir object; sodalite is also used for beads, cabochons, and ornamental stone.

Geological facts

Sodalite is named for its sodium content and commonly has white calcite veining. Strong, uniform blue color can indicate dye or another blue stone.

Field identification & locations

Check for natural color variation and veining, and test hardness or streak only with permission; visual identification is uncertain. Sodalite is found in Canada, Brazil, Namibia, and Russia.
