Sterling Silver Gemstone Necklace with Magnetic Lock 18.5" Long

Most 18" necklaces hang on my neck, so I was sure that this would be a good layering piece, especially since the description said that it was 18.5" long. However, when I received it and put it on, it turned out to be a choker. It is pretty and I will keep it, but won't be able to use it as I intended. Will have to look further for a longer gemstone necklace. Sad
