This stunning necklace is handcrafted using a 20mm round glass cabochon set within a nickel free silver tone setting. The pendant comes with an 18" nickel free silver tone link chain with a lobster clasp. The total length of the pendant, including the bail, measures 1 1/2". This item is water resistant, but I would not recommend showering, swimming or other prolonged exposure to water while wearing it to prevent any damage.
