Lab-Grown Diamond Engagement Ring
Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous beam that seems to stretch beyond the hand. This semi-set engagement ring invites you to choose a 6 x 3.5 mm marquise center, its tapered points echoing a quiet drama framed by four delicate side stones.
Crafted in warm 18K yellow gold, the band is shaped for everyday grace—comfort fit with a subtle curve that rests naturally against the finger. The five-stone arrangement balances sparkle and sophistication, while the low-profile setting ensures ease of wear beneath gloves or alongside stackable bands.
Each ring is finished by hand in our Williamsburg studio, where precision meets patience: every prong is inspected to cradle your chosen diamond securely, and the gold is polished to a soft glow that deepens with time.
Our commitment to ethical jewelry is reflected in the lab-grown clarity of your marquise diamond, offering brilliance without compromise on sustainability.
This design suits those who appreciate refined geometry with a romantic edge—elongating the hand while maintaining a delicate presence. The semi-set format allows you to select a stone that resonates personally, making the ring uniquely yours.
