I love this necklace - it's going to be tough to let it go!  The charm is a reworked dress clip from the Edwardian era.  Beautiful fine metal work design encase bright paste stones and I have hung it from a long delicate 22ct gold plated chain.  Easily worn solo or layered with shorter chains.  It works perfectly with one of the smaller, shorter Edwardian cluster necklaces.  Works day to night.  Total length is 22 inches.
