The Ultramarine Necklace is 18 inches long and built from 12 strands of traditional Czech Preciosa Ornela seed beads — some of the finest glass beads made, known for consistent size, shape, and depth of color. Three magnetic clasps make it easy to put on and take off, and the strand construction means it drapes with a satisfying weight and texture. Each necklace is assembled by hand. Care: store in a cool, dry place. Avoid moisture and direct sunlight. Clean with a dry cloth.
