If you’re into clean lines and that sleek, modern vibe, emerald-cut diamonds have it all. With their long, rectangular shape and step-cut facets, they don’t sparkle in the same way as round or princess cuts. Instead, they give off this cool, mirror-like shine that stands out without being flashy. The shape makes the diamond look big and bold on the finger. A simple solitaire or a ring with extra details, an emerald-cut ring never goes out of style.
