The Metal Beyop Disc is basically a traditional ornament attached to Adi tribes, an indigenous community in Northeastern India, particularly in Arunachal Pradesh. This metal disc holds cultural value as well as aesthetic value and is frequently flaunted with accessories in all festivities, ceremonies, and daily life.
The Beyop disc is made through the casting technique, a technique that has been handed down over generations. Traditionally, artisans rely on brass, copper, or other forms of metal for producing the discs into different interesting shapes. Casting refers to the melting and pouring of metal into pre-made molds and allowing it to cool as a form before refining it further into the final product. The polished disc is then sewn on the garments or jewelry and serves as an identity- and heritage-marking object.

For all the people of the Adi community, ornaments like Metal Beyop Discs have a social and symbolic importance besides being just for ornamental purposes. They usually denote a person's social status, their marital status, or clan affiliation. The motifs on the disc may have features that relate to nature and might be from folklore or tribal mythology, showing how the tribe is deeply related to its environment.
The modern trends overshadowed the traditional, and efforts, however, were being made towards conserving and promoting the art of the Adi tribes. Local artisans still keep making these discs in their ancient ways, carrying forward this heritage of rich cultural inheritance that the Adi have.
