Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with quiet drama. This semi-set halo engagement ring offers a refined foundation for a 10 x 5 mm marquise center, designed to balance presence with everyday ease.

Crafted in warm 18K rose gold, the band’s low-profile setting ensures the halo frames the stone without excess height, making it comfortable beneath gloves or daily wear. The smooth finish and precise prong work reflect careful hand inspection, promising durability alongside elegance.

Each diamond is lab-grown, embodying clarity and brilliance while aligning with a sustainable approach to fine jewelry. This ring suits those who appreciate architectural grace paired with practical comfort, especially for slender to medium finger shapes where the marquise’s length enhances natural hand lines.

Should you need a custom fit, resizing is available with minimal turnaround, preserving the integrity of the delicate halo. Whether layered with stackable bands or worn solo, this design adapts seamlessly to a modern lifestyle.
