Each of Mikimoto's cultured pearl strands are a work of art born from the mystery of the sea. Creation of these strands requires incredible skill, judgment and craftsmanship. The journey begins with a rigorous selection process, culling the very best quality pearls. This 18” Akoya cultured pearl strand features anywhere from 6.5-8mm Akoya cultured pearls with a Mikimoto signature clasp in 18K white gold.
