A 3-carat heart-shaped diamond is perfect to showcase your romantic feelings with a visible impact. The size of the diamond affects the clearly defined outline of the shape that makes its iconic silhouette stand out. It's great to prioritise cut, color, and clarity for these diamonds to shine brilliantly and avoid inclusions and blemishes. This shape is usually special for someone who wants a sparkle that's timeless, expressive, and unforgettable.
