A very fine French Belle Epoque 18K yellow gold brooch set with diamonds, blue sapphires and demantoid garnets around a central sugarloaf cabochon 3.59-carat peridot. The demantoids exhibit the desirable horsetail inclusions characteristic of Russian stones. The combination of blue sapphires and the bright grassy green of the demantoids and peridot is very pleasing. All the smaller stones are old mine cuts. Six small rose-cut diamonds are collet-set in silver. The back retains the original c-clasp and extended pinstem which is fully stamped with French "tete d'aigle" hallmarks for 18K gold and with an illegible goldsmith's mark.
