14k Yellow Gold Ring with Natural Morganite & Lab Grown or Natural White Diamonds. Crafted in 14K solid yellow gold, the Isla Morganite Ring centers on a pale pink step-cut morganite with white diamonds set tightly around it. The contrast between the stone's soft color and the crisp diamond border gives the ring a graphic, almost architectural look. Diamond details continue down the sides of the setting, keeping the focus on the center while adding texture from every angle.
