Necklace made by MIKA. I’m not familiar with this brand. Two layer necklace featuring one metal plated cowrie shell and nine natural cowrie shell strung in cord. This has some goldtone color loss / wear on metal parts. No wear on goldtone Shell. Short chain measures approx 14 1/4” - 17 1/2” Other necklace is approx 2”-4” longer. Idk. Hard to measure.
