An absolute favorite of mine and whilst trawling through antique markets I've yet to find another butterfly similar to this.  I've adapted the vintage 3d cotton butterfly brooch and attached it to a delicate 16ct gold plated mixed link chain.  Adding some detail, I have placed a tiny vintage Japanese faux pearl eitherside of the butterfly and one by the clasp.  Wear this bracelet in a stack alongside contrasting styles or simply on it's own.
