Jade And Sterling Brooch - Gumps

This is a beautiful brooch from an estate. Sterling silver with gold vermeil, it measures about 2-3/4" long. It is set with green cabochons which I believe are jade. I have not had this appraised so the stone id may not be correct.  The back is marked Japan Sterling For Gumps (Gumps Department Store). Gumps only handled the best so you know this is quality.  Picture really does not do it justice. The stones are just gorgeous.
