These are Swarovski crystal earrings in four prong settings of either silver or gold. We can set a great variety of colors. If you are looking for a specific color, please let us know! We'd be happy to create your special pair. Please note: the settings for these earrings are either a gold-plated brass (if gold colored) or a stainless/surgical steel (if silver colored) setting. Higher quality metal settings are available if prefered. Please email us if you prefer a different metal. We have options we'd love to discuss with you! For size reference these are an SS39 which are approximately 8mm in size, which is approximately the size of the negative side on a AA battery. The posts are either silver or gold plated brass, very low lead or nickel content and safe for most ears (including sensitive). These are a fun everyday addition to your jewelry collection!
