Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the length of the finger with subtle drama. This semi-set halo ring offers a handcrafted foundation in warm 14K yellow gold, designed to cradle a 12 x 6 mm marquise center stone with precision and care.

The band’s smooth finish and delicate halo setting are shaped in our Williamsburg studio, where each curve is refined for everyday wearability. The low-profile design ensures comfort beneath gloves or alongside stackable bands, while the secure prong setting balances protection with light’s full passage through the stone.

Crafted around a lab-grown diamond, this ring reflects a commitment to ethical jewelry—minimizing environmental impact without compromising brilliance or clarity.

Its elongated marquise shape lends a graceful elongation to the hand, ideal for those who appreciate a blend of vintage-inspired elegance and modern craftsmanship. The semi-set nature invites you to select a center stone that resonates personally, making each ring uniquely yours.
