This symmetrical cut is engineered to produce exceptional brilliance, fire, and scintillation, making it the most recognized diamond shape worldwide. Advanced technology ensures that each lab grown round shaped diamond achieves optimal proportions for sparkle and durability. As a result, it combines precision craftsmanship with sustainable origins of lab grown diamonds in the UK, offering beauty that suits both modern and traditional jewellery designs.

 

 

Carat Weight Appearance in Round Diamonds

 

Carat weight plays a key role in how a round cut lab grown diamond appears, but size perception can vary depending on its cut proportions. A well-cut stone with an ideal table and depth will look brighter and slightly larger than one with poor symmetry. Because of their balanced shape, round diamonds often appear smaller face-up than elongated cuts like oval or marquise of the same carat. This makes it important to focus on both cut quality and measurements rather than carat weight alone when selecting a stone.
