4 Carat Oval Cut Blue Lab Grown Diamonds

A 4 carat blue oval is stunning. The elongated shape sweeps blue across a large face-up area, creating an oceanic, sapphire-rivaling presence at this exceptional size.

The elongated shape spreads blue across more surface than any compact shape at the same weight. At 4 carats, the blue sweeps dramatically across the finger with intense brilliance.
