This cabochon turquoise necklace from designer Irene Neuwirth is in an 18 karat yellow gold, scalloped and notched, tiny milgrain edged setting. The stones are the color of spring. The designer's secret for making sure this necklace lays perfectly? Look closely and you will see that each stone is mounted slightly higher than the center, so that when you put it on the correct way, it can't flip. Simply brilliant. 34" with safety clasp.
