For sale is this extraordinary, and rather rare, 14k yellow gold filigree framed cameo of Leda and the Swan (Zeus in disguise) or Hebe and the Eagle (also Zeus in disguise) that Zeus got around. The fine filigree frame measures a whopping 2 3/8" x 1 3/4" and still has its original "T" pin and folding clasp. Normally the clasp would be signed, but the only mark I can see is the "star" mark shown in the second last picture. Because it is not very clear, it has been carefully acid tested to be at least 14k gold, but I suspect it has a higher gold content as it took a very long time for the 18k acid to show any effect. The carving is hand done and exquisite with no cracks, chips or damage. There are some interior stress marks over her right shoulder, but they are merely a sign of age are not damage. The piece weighs 14.7 grams and the shell is rather thin. The brooch dates to the 1860's. While it could possibly be an eagle, I feel it more strongly resembles a swan.
