Measuring 18 inches in length, this sterling silver 3mm Caspia™ necklace can be used on its own or combined with other beads and charms for beautiful results. Use this chain with Large Hole Murano Beads for wonderful results. The end of the necklace screws off and the beads fit perfectly. Add 8mm smart beads, and the Murano glass beads will remain in place. This Caspia™ necklace has a classic look and is great for both men's and women's jewelry. This is high-quality sterling silver and will not wear off like silver-plated chains. Note: If the end is screwed too tightly it can break off.
