Naid In Greek mythology the Naiads were water nymphs who presided over lakes, fountains, springs and streams. The waters where Naiads lived were thought to be endowed with inspirational, medicinal, and prophetic powers and were worshipped by the Ancient Greeks. Naiads were famous for their natural beauty, and classical literature is filled with their love affairs with gods and men. Inspired by these aquatic sirens, Naiad jewellery is decorated with freshwater pearls and opalites.
