Cheap bowls (under $15 wholesale) are machine-cast brass from India, often polished to look like hand-hammered. Mid-range ($20–$60 wholesale) are hand-hammered in Nepal by a single artisan over 1–2 hours from bronze. Premium bowls ($100+) are antique or made from true seven-metal alloy with documented provenance. Price tracks labor hours and alloy cost, not marketing.
