This stunning necklace is handcrafted using a 25mm x 18mm oval glass cabochon set within a nickel free silver tone setting. The pendant comes with an 18" silver tone link chain with a lobster clasp. The total length of the pendant, including the bail, measures 2 1/4". 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.
