Hooray for May and its beautiful birthstone—emerald! Featuring this vivid green shade, this birthstone necklace, which also comes complete with a cross and heart design, is great for religious jewelry and gifts. Fun fact, emerald is thought to signify wisdom, growth and patience. With so many positive virtues associated with it, it'd be no surprise if you snagged one of these necklaces for yourself too! Pewter. 1" pendant on an 18" metal chain.
