This 1.42 CT radiant cut halo lab-grown diamond engagement ring features a radiant-cut center stone secured in a four-prong arrangement designed to stabilize the rectangular outline while maintaining balanced height across all corners. The radiant cut’s facet structure is oriented to align with the axis of the 18K gold band, supporting proportional symmetry from the top view.
Surrounding the center stone is a halo of round lab-grown diamonds arranged in a rectangular perimeter. Each round accent stone is placed in an individual prong seat engineered to follow the outline of the radiant center stone. The halo maintains uniform spacing and consistent height around the full perimeter, forming a continuous upper surface without excessive elevation.
The band incorporates round lab-grown diamonds positioned along the upper shank in a pavé-style configuration. Each accent stone is secured in a dedicated seat with micro-prongs calibrated to maintain alignment and uniform height. The pavé placement extends seamlessly into the halo, creating a continuous transition from the band into the central setting.
An open gallery beneath the center stone and halo allows controlled light entry from below, supporting consistent optical behavior across both the radiant-cut center diamond and the surrounding round accent stones. The underside of the band remains smooth to preserve structural integrity and wearing comfort.
All diamonds in the ring are lab-grown and graded under standardized frameworks for color, clarity, and cut.
The 1.42 CT total weight includes the radiant-cut center diamond, halo diamonds, and all pavé-set accent stones along the band, resulting in balanced surface coverage and a defined halo profile.
For an in-depth explanation of how cut precision influences brilliance and light return in radiant and halo designs, refer to the Diamond Cut Quality Guide. Shape-specific considerations for radiant outlines, halo interaction, and proportional balance are detailed in the Diamond Shapes Guide. Broader evaluation guidance on selecting lab-grown diamond engagement rings, including halo construction and long-term value considerations, is outlined in Global Lab-Grown Diamond Buying Guide (Official Buvea Edition).
This configuration supports a radiant-cut center stone with a rectangular halo and pavé-accented band in a balanced, low-profile engagement ring design.
