This simple mother of pearl pendant hangs on an 17 inch gold fill satelite chain with extender. It looks stunning on its own or layered. 
 
All Rock Me Designs findings (chain, earring hoops, earring hooks, clasps) are made of sterling silver, or 14K gold fill. Gold Fill is a base metal fused with gold so will not fade over time, and will be suitable for those who are hypoallergenic.
