A sand dollar necklace with a blue bead and an 18" adjustable chain is a delicate and coastal-inspired piece of jewelry. The centerpiece of the necklace is a small, intricately designed sand dollar pendant, often made from silver, gold, or white resin to mimic the natural texture of a sand dollar. Above or near the sand dollar, a blue bead is added, typically in a turquoise or deep ocean blue color, which complements the beach theme and adds a pop of color.

The necklace features an 18-inch adjustable chain, allowing the wearer to customize the length slightly for a perfect fit. The chain is usually thin and understated, designed to highlight the beauty of the pendant and bead. This type of necklace is perfect for casual wear or for someone who loves the ocean and nature-inspired accessories.
