"Folded Leaf" drop earrings, made using a technique known as Fold Forming - basically its like origami with metal.  
The drop earrings shown are all Sterling silver but the middle ones are gold vermeil (gold plated silver) and the pair on the right are oxidised to turn them black.
The length of the leaf is approximately 35mm plus the shepherds crook ear wire.  I make them in various lengths to fit your requirements.
