An engagement ring like no other. An SI1/F, emerald-cut, 1.5-carat diamond presides in the center, while two half-moon diamonds, totaling an additional half-carat, shine from either side of it. 64 more brilliant round diamonds -- three-quarters of a carat in all -- line the intricately designed shank. A gorgeous gallery completes the picture, but it's never truly complete. You'll gaze at this piece of art for decades to come, always discovering something new.
