Black Beads: The chain is primarily made of small, black beads interspersed with the silver chain. These beads are traditionally made of black onyx, glass, or enamel. In Hindu tradition, these black beads are believed to have protective qualities.
Gemstones/Crystals:
Diamonds: The large, central stone in the pendant and on the earrings appears to be a diamond. The smaller, surrounding stones also appear to be diamonds, set to create a sparkling, halo effect. The diamonds could be natural or lab-grown.
Gemstones: There are smaller, colored stones, which could be emeralds (green) and rubies (red) or other precious/semi-precious gemstones. They are used as accent stones to enhance the design.
