Vintage Blue Glass And Chain Necklace

I am not sure what this dark blue 6-stone beauty was originally.  It had small loops to the top and bottom and is set on a brass backing. 

Originally I had hopes of making a pair of earrings as there are two of these.  But it was too heavy so I changed course and have used chain to form a necklace instead.  The pendant is suspended from chain which meets at a central ring and I created a loop out of chain to the base.

Please see the video as the colour is wonderful.
