Chinese turquoise has interesting variations in color and matrix pattern. The hand polished, large rondelle beads I used in handcrafting this necklace are no exception; they are really differient. I also used 6 mm round beads Chinese Turquoise beads and a sterling silver hook and eye clasp in creating this necklace. The necklace is about 25" in length and the rondelles are about 5/8" in diameter. Lots of black matrix makes for unique patterns in the beads!
