These beads have the perfect green mottling that signifies Peking glass. The necklace has small (1/4" diameter) and large (1/2") balls and long tubes (1 3/4"). The large balls and tubes have elaborate filagree findings. Wearable length 29", drop 4 1/2". A wonderful flapper necklace. I think it's brass and Czech. One little ding to a ball. Excellent vintage condition.
