What Makes Lab Grown Marquise Cut Diamonds Unique?

Lab grown marquise cut diamonds combine the striking, elongated shape of the marquise with the sustainable advantages of modern technology. Their boat-like design creates a larger face-up appearance, giving maximum brilliance for the carat weight. Ethically created in controlled labs, these diamonds match mined stones in durability and sparkle while offering exceptional value. This makes them an ideal choice for eco-conscious buyers seeking both beauty and responsibility.

 

 

How to Select the Right Marquise Lab Grown Diamond?

 

When choosing a marquise shaped lab grown diamond, pay close attention to symmetry, as uneven points can affect its overall look. Check for minimal “bow-tie effect” in the center, ensuring balanced brilliance across the stone. Consider the length-to-width ratio to match your style preference—whether a slender or wider shape. Always review the 4Cs with extra care on cut quality, as it defines sparkle and elegance in this unique shape.
