Here I combined turquoise rondelles and turquoise heishi to create this 27" necklace. The heishi is about 6 mm in diameter by 2 mm. The turquoise rondelles and heishi are about 8 mm and 4 mm respectively. I alternated the rondelles and the heishe 20" with the balance of the length being make up of turquoise heishi and the sterling silver findings including cones and a toggle clasp.
The turquoise rondelles are a pretty blue with black matrix and are likely from China.
