Collectors often choose marquise aquamarines over traditional round cuts for their distinctive elegance and efficient use of rough crystal. The elongated shape maximizes perceived size, making a one-carat marquise appear larger than a one-carat round stone, offering better value per carat. Marquise aquamarines create a slimming effect when worn on the finger and provide unique design opportunities in custom jewelry. Additionally, the shape often works well with aquamarine’s typical crystal structure, allowing cutters to preserve more of the original rough while showcasing the stone’s natural beauty and color.
