This earring is part of my CAIRDEAS collection of pieces that incorporate circular domes. The collection symbolizes love, loyalty and friendship. This piece shown in this photo has Nephrite (BC Jade) set behind sterling silver, for a window effect. It has a sterling silver post and butterfly back. This onesy can be paired with another to make interesting set - just make sure to check the number of links in the dangly chain if you want them the same length. This one has 5 links.
