A 3 carat lab diamond is a precisely engineered stone created using advanced technology to mimic the structure and beauty of mined diamonds. They are categorized as man made diamonds and have identical physical, chemical and optical properties with natural gems. They are about 9.3mm in diameter and have striking size and brilliance. At Flawless Fine Jewellery Hatton Garden, London or Manchester, each 3 carat stone is graded for cut, colour, clarity, and carat weight, and therefore exceptional quality is guaranteed to create high impact jewellery designs.
A 3 carat lab grown diamond offers a wide choice of design styles with shape being a significant determinant of overall look. The oval cut diamond, the round brilliant, the emerald and cushion cuts are the most popular where each one adds the sparkle in their own unique manner. Such a large artificial diamond exudes excellent presence, and therefore pairing it with the right setting like solitaire, halo, or three-stone, accentuate its brilliance and look. The oval and elongated shapes can form a bigger visual spread, whereas round cuts will give the maximum fire and symmetry. Selecting the right shape ensures the diamond complements both personal taste and hand proportion.
