Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, graceful shadow across the hand. This semi-set halo engagement ring frame awaits your choice of a 10 x 5 mm marquise center, designed to amplify the stone’s tapered drama with a delicate circle of pavé accents.

Crafted in warm 18K yellow gold, the mounting balances a low-profile silhouette with secure prongs, ensuring daily wearability without catching. The band’s subtle taper and smooth finish offer a comfortable fit that slips easily beneath gloves or alongside stackable rings.

Each piece is meticulously finished in our Williamsburg studio, where expert hands inspect every facet of the setting for precision and durability. The lab-grown diamond option reflects a commitment to ethical jewelry, reducing environmental impact while maintaining exceptional clarity and brilliance.

Ideal for those who appreciate architectural elegance paired with practical design, this halo setting enhances the marquise’s elongating effect on the finger. Its semi-set nature invites you to select a center stone that speaks personally, making the ring uniquely yours.

Resizing is straightforward and handled in-house to preserve the integrity of the setting. Typical lead times accommodate careful craftsmanship without rush.
