Among the indigenous groups of Arunachal Pradesh, India, the Adis have historically worn the metal armlet, a classical ornament. This armlet, usually made of metal through casting, is exquisitely engraved with intricate geometric designs, which must showcase the rich artistic investment of the tribe and their outlook on culture, which goes into the creation of the designs themselves.
Typically, the metal armlet is made in brass, copper, or silver using lost wax casting or sand-casting methods. Ancient geometric designs etched across the surface symbolize protection, status, and tribal identity. The process starts with heating the chosen metal, melting it , pouring it into prepared molds, and carving out the details, creating an ornament that is stunningly beautiful and remarkably long-lasting.

Men and women of Adis wear this on essential occasions, including festivals and ceremonies. The armlet is not ornamental but holds strength, prestige, and pride within the community. Some armlets are believed to have protective or spiritual significance and protect the wearer from negative energy and bring good luck as well.
Such modernity does bring traditional ornament-making to waning heights among the Adi. Nonetheless, this craft is alive and flourishing through inputs from local artisans and cultural organizations, also bolstered by government support. The metal armlet is thus an important symbol of Adi craftsmanship, proving their belonging to the tribe's heritage and artistry.
