Labradorite hummingbird necklace (Pendant and Chain)

Beautiful humming bird with labradorite i dont know what the metal is, but I have had it for a few years, and it has not changed color. I couldn't show the beautiful shine and colors of the humming bird in the pictures, so please see the video for a better view of it. the pendant is about 1 inch, and with the chain, it comes to ablut 10 inches. For me, it sits right at my chest and looks beautiful with a tank top.
