Four-strand emerald bead and diamond rondelle necklace

Composed of 309 fluted emerald beads measuring approximately 12.1 by 4.8 mm. in diameter, arranged in four graduating strands, accented at intervals by gold rondelles set with small round diamonds, the rectangular clasp centering a cushion-shaped carved emerald flanked by round and baguette diamonds, the total diamond weight approximately 3.25 carats, lengths of strands approximately 17 to 20 inches. 

Good condition. The emeralds are an attractive, richly saturated medium green and are well-matched. They are moderately included with some inclusions breaking the surface resulting in some chips and cracks that are typical to this type of material. The diamonds are H-K color, SI-I clarity.
