4 Carat Radiant Cut Blue Lab Grown Diamonds

Dramatic. Intense blue sparkle across the rectangular body. At 4 carats, the radiant's brilliant faceting creates dynamic blue fire that's livelier than step-cut blue. Sapphire-rivaling.

The brilliant faceting scatters blue into intense sparkle, creating a dynamic, electric blue different from the calm depth of emerald-cut blue. At 4 carats, the effect is dramatic.

Blue lab diamonds are extremely rare and highly prized. white gold or platinum enhances the cool blue tones. For a 4 carat radiant cut, consider a setting that allows maximum light entry to intensify the blue saturation. Simple solitaire or minimalist settings work well because they keep the focus on the rare color rather than competing design elements.
