Vintage Cultured Pearl Necklace with 14k White Gold Clasp

Beautiful cultured pearl two-strand necklace with ornate, pearl studded clasp of 14k white gold. Two strands (may have been 3 or 4), 18.5" and 20" inches clasped. The pearls start tiny and graduate to small at the bottom. Excellent condition (in photo 4 there's an orange spot which was easily brushed off and is now gone).
