Shankha Carving (Conch Shell)

শাঁখা (Shankha); শাঁখারি শিল্প (Shankhari Shilpa)

Shankha is the traditional Bengali Hindu art of carving, cutting, and shaping sacred conch shells (Turbinella pyrum) into ritual bangles, figurines, and decorative objects. The white conch-shell bangle (shankha) paired with the red lac bangle (pola) constitutes the mandatory bridal adornment of the married Bengali Hindu woman — a deeply embedded cultural identity marker worn from marriage until widowhood. The Shankhari community (caste-specific craftspeople) of Shankharibazar, Dhaka (now Bangladesh) and North Kolkata are the hereditary practitioners. The carving involves cutting and grinding the dense shell to produce smooth, carved, or pierced bangles and ornaments using iron saws, grinding wheels, and fine chisels. The technique is critically endangered: synthetic plastic imitations dominate the market, Turbinella pyrum is CITES-regulated, and the Shankhari community is declining sharply.
