Key Trinket Hummingbird Necklace

A vintage key with a brass hummingbird and a sparkly piece of quartz crystal, all hanging on a beautiful filigree antique brass chain.  The key has the number 178 stamped on it.

Chain measures approximately 25 inches.  Key is about 1.25 inches long.

These are vintage keys (some may be antique and not vintage, I don't have exact dates for them), and they have signs of age to go with it, so please look closely at the photos.
