Cameo Pendant Necklace Root Beer Colored Face w/ Peridot

Vintage oval shaped filigree base with what appears to be an acrylic, resin-like brown translucent cameo with the silhouette being a right face. Prong set. Concave bottom curvature lined with AB crystals and a solitaire green Peridot with lots of brilliance! The length is a little bit between 1.25 - 1.50" Chain is about 24". I've had this for a long time, but I just don't get dressed up as much as I used to, and my jewelry armoire is overflowing. It's too beautiful to be tucked away in a box. I've only found one comparable piece in my internet search, I'm going to include that photo in the gallery here.
