A 3 carat solitaire diamond ring is the type of ring to build a dream on. Sleek, plain metal bands that curve upwards towards a center stone encased in lustrous prongs, 3 carat solitaire diamond rings speak to the height of sophistication. A hallmark of elegance and luxury, these engagement ring styles are simply and effortlessly chic. Choose from a wide array of shapes including round, oval, cushion, princess, pear, emerald, asscher, heart, marquise, or radiant to create a 3 carat solitaire diamond ring that is uniquely you.


If you're hoping to pair a classic 3 carat solitaire diamond ring silhouette with extra sparkle, consider choosing an engagement ring setting with a hidden halo of diamonds. From the top down, hidden halo styles are traditional: from other angles, they glimmer more brightly. If you're searching for extra unique 3 carat diamond solitaire ring, consider creating a custom, one-of-a-kind design.
