Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a slender, luminous shadow across the hand. This semi-set engagement ring invites your choice of an 8 x 4 mm marquise stone, its tapered points echoing a quiet elegance that feels both intimate and striking.

Crafted from warm 18K yellow gold, the mounting features a delicate solitaire setting designed for everyday wear. The low-profile prongs cradle the stone securely while maintaining a graceful line close to the finger, ensuring comfort and ease beneath gloves or alongside stackable bands. Each ring is meticulously finished by hand in our Williamsburg studio, where precision meets subtle artistry.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, offering clarity and brilliance with a reduced environmental footprint.

The slender shape of the marquise naturally elongates the finger, making this ring a thoughtful choice for those who appreciate refined geometry and a touch of vintage-inspired romance. Its adaptable silhouette pairs effortlessly with other rings or stands alone as a statement of quiet devotion.

Should you need resizing or prefer a custom stone selection, our Brooklyn studio offers personalized consultations to ensure your ring fits perfectly and reflects your vision.
