Carved blue stone figurine, likely dyed or treated sodalite
Sodalite, Na₈(Al₆Si₆O₂₄)Cl₂ (tentative identification)
AI-generated identification · may be incorrectOpaque, 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.
