This black pearl floating necklace is a simple, pretty design that you will reach for over and over again. In this style, a dark, blue-black freshwater pearl slides along gold filled chain. The pearl measures about 7mm and sits right at the hollow of your throat, making this a great layering piece. Tiny silvery pearls connect the lobster clasp. This necklace is about 16 1/2" (42cm) in length, which is a little longer than the usual choker length. If necessary, I would be happy to adjust it for you at no extra charge. Also available in sterling silver. Your jewellery will be packaged in a small gift box. Gift wrapping is available upon request. What is Gold-Filled? Gold-filled is an economical alternative to solid gold. By law, it has 1/20th by weight layer of 14 karat gold permanently bonded over a core of base metal. It is tarnish-resistant, safe for sensitive skin and unlike gold plate, it will not wear off. It is a great way to enjoy affordable gold jewellery.
