What Is a 4 Carat Heart Cut Lab Grown Diamond?
The heart cut is a modified brilliant cut featuring 56–58 facets engineered to maximise brilliance while showcasing a distinctive and symbolic shape. Its appeal lies in its symmetry — a well-defined cleft, balanced lobes, and rounded curves that create an instantly recognisable profile. At 4 carats, the heart shape offers striking presence, exceptional fire, and a luxurious surface area that enhances visibility and brilliance.
