Textured gold color shield shaped base with an applied big cat holding a royal blue rhinestone in its teeth. Looks like a lioness, then I see a tiger. It's a big and beautiful piece. The tiny pin in the hinge has been replaced, looks to have been done years ago and is a bit unorthodox with the stem wrapping around the hinge. Not visible from the front and functions perfectly. Ca., 1900 and is in very good condition.
