This is a luxurious and voluminous necklace featuring multiple strands of beads carefully layered and held together by a gold-tone clasp and chain extender at the top. The necklace utilizes a sophisticated blend of complementary colors and materials:

Several strands are composed of small, creamy pearlized beads. The remaining strands feature two distinct colors of small gemstone: a soft mauve pink and a vibrant emerald green. Traditional, festive, and luxurious. It strongly suggests classic Indian or South Asian jewelry design.
