Antique Edwardian 10k yellow gold filigree cameo brooch pin. Measures 1-1/2" x 1-1/4", the hand carved shell cameo itself measures 1-1/8" x 7/8". Hallmarked "10K" on the clasp and also maker marked on the pin stem. In excellent condition, no chips, cracks, or hairlines. All natural cameos when held to strong light will show very fine growth lines. These are neither hairlines nor cracks, they are natural to the shell and unique to each individual piece. Circa 1910.
