Dramatic. Deep blue through chunky, romantic fire. At 4 carats, the pillow-like shape with sapphire-rivaling color creates a commanding, sophisticated statement.

The broader facets create chunky, saturated blue flashes. At 4 carats, each broad flash shows rich blue with romantic depth.

Lab growing allows more consistent blue coloring than nature. At 4 carats, the larger stone size allows the blue hue to display with greater depth and saturation than in smaller stones. The cushion cut's larger facets with rounded corners in a pillow-like shape distribute the color evenly across the face. Lab growing technology allows precise color control, producing consistent blue tones.
