The Beads: The chain is composed of small black beads (typically made of glass, onyx, or plastic). In Indian tradition, these beads are believed to ward off the "evil eye" ($nazar$) and protect the marriage and the husband's well-being.

The Pendant: This specific design features a triangle-shaped pendant with a minimalist, geometric aesthetic. Traditional Mangalsutras often feature two gold cups (called vatis) or floral motifs, but modern versions like the one in your photo are designed for everyday wear and versatility with Western and ethnic outfits.
