Key Quartz Necklace

A vintage key with a sparkly piece of quartz covered in a swirly bead cap. Everything is on a stainless steel chain. 

Chain measures approximately 30 inches.  Key is about 1.75 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.
