timeless choice for engagements and everyday wear.

reflect light exceptionally well. In lab grown diamonds, this cut performs just as beautifully
as it does in mined diamonds.

chipping and ideal for daily wear in engagement rings and wedding bands.

prong settings. The shape is versatile and complements both minimalist and detailed designs.
Do round cut lab grown diamond rings look smaller than other shapes? +

shapes may appear slightly larger for the same carat weight, the round cut usually offers
the most lively, even sparkle across the surface.
