Faux Topaz Juliana Vintage Brooch

I have to say this is one of the most beautiful Juliana brooches that I've come across. It had just been put out & I was lucky enough to grab it! The thrift shops here seem to just look to see if the piece is signed, if not they mark it very low, for which I'm very glad! My night photos don't capture the dazzling colors too well. It measures 2 3/4" x 2 1/4".
