The necklaces come with sterling silver chains. Each item is handmade so variations will occur.
They are complex and may not look perfectly symmetrical, and that gives them a certain charm. Your piece might be made to order. In which case, please allow a few days for making. The filigree jewellery is entirely handmade from 925 silver wire and cubic zirconia unless it contains pre-loved, vintage or even antique pieces; those are from unknown metals, often some degree of silver but not always. Be aware of how your skin reacts in case of some form of metal allergy and in that case discontinue use.
