These antique Hebron beads are very old possibly as early as 1200 AD and definitely show their age. This deep Turquoise color is very rare as these beads are most commonly found in yellow or brown. Adjustable from 17 to 21 inches this lovely necklace was constructed using 27 individual Ancient Hebron Turquoise Glass Beads graduated from 15mm X 25mm center bead to 9mm X 15mm end beads, with 3 mm natural turquoise nugget spacer beads. When I first saw these beads I mistook them for real turquoise, and I have seen a lot of turquoise. The necklace has a sterling silver extender chain and a lobster claw closure. Total weight is 201 grams.
