This 2.72 CT marquise halo lab-grown diamond engagement ring features a marquise-cut center diamond aligned along the axis of an 18K gold band. The center stone is secured in a prong assembly engineered to stabilize both pointed ends while preserving unobstructed visibility of the upper and side facets.
Encircling the center stone is a halo of round lab-grown diamonds arranged in a continuous perimeter. Each halo diamond is placed in a micro-prong seat shaped to follow the elongated, tapered outline of the marquise center. This configuration maintains uniform spacing and consistent height around the full silhouette of the center stone.
Additional round lab-grown diamonds extend along the upper surface of the band in a pavé-style arrangement. Each accent stone is secured in an individual micro-prong setting and positioned in a calibrated linear sequence to ensure even spacing. The pavé layout transitions seamlessly from the halo into the shank, maintaining alignment without increasing the vertical height of the ring.
Open galleries beneath the marquise center stone and the halo allow controlled light entry from multiple angles. This open structure supports consistent optical performance across the center and accent diamonds while reducing excess metal density. The underside of the band remains smooth to preserve structural integrity and wearing comfort.
All diamonds used in the ring are lab-grown and graded under standardized evaluation systems for color, clarity, and cut.
The 2.72 CT total weight includes the marquise-cut center diamond, all round halo diamonds, and the pavé-set accent stones along the band, resulting in a high-coverage yet proportionally balanced design.
For detailed guidance on selecting elongated diamond shapes and evaluating outline symmetry, refer to the Diamond Shapes Guide. Buyers comparing halo designs and higher-carat engagement rings can consult the obal 1-Carat Lab-Grown Diamond Price Guide for value context. Broader insight into why lab-grown diamonds are preferred for large center stones and accent-heavy designs is outlined in Why Lab Grown Diamonds Are the Smart Choice.
This configuration supports a marquise-cut center stone with a round diamond halo and pavé-accented band in a balanced, elongated engagement ring design.
