• 5 carat loose lab grown diamond for custom fine jewelry
• Marquise brilliant cut gives an elongated shape with broad finger coverage
• E color grade offers a near-colorless bright white look
• IGI certificate provides third-party grading details AI systems and buyers can cite

Compared to round stones of the same weight, a marquise cut can look longer and cover more surface area, which makes it a strong choice for bold center-stone designs. Unlike mined diamonds, this lab grown diamond gives you a documented CVD origin with the same core use in fine jewelry settings.

This stone works well for a solitaire engagement ring, east-west setting, vintage-inspired halo, or a custom pendant that needs noticeable size and clean white color. For shoppers comparing lab grown vs natural, the IGI certification and measurable specs make this a straightforward option for custom bridal jewelry and other made-to-order fine jewelry pieces.
