A 4 carat dutch marquise the wider proportions create a distinctive vintage presence on the finger. The blue hue is extremely rare and highly prized, adding collectible appeal. 4 carat lab grown diamonds are very significantly above the average lab diamond size in the USA and look amazing if going for a large diamond look. The dutch marquise cut's wider and more rounded than a standard marquise, with an antique character commands attention at this size.

white gold or platinum enhances the cool blue tones. At 4 carats, the blue hue is prominent enough to be the star of the ring, so minimalist settings often work best. East-west settings, vintage-inspired prong designs, and ornate solitaire mounts all complement this stone well. Avoid overly ornate designs that compete with the rare blue color.
