How do you identify an ashtadhatu idol?

An ashtadhatu idol is identified by its composition, which includes eight metals: gold, silver, copper, lead, tin, zinc, iron, and Mercury. These metals are traditionally believed to enhance the idol's spiritual properties. The idol usually exhibits a distinct luster and intricate craftsmanship, often featuring religious or mythological motifs. Additionally, ashtadhatu idols are typically heavier than those made of a single metal, indicating their composite nature.
