Lab-Grown Diamond Engagement Ring

Sunlight catches the emerald-cut center stone’s broad, glassy facets, casting a serene glow that feels both architectural and intimate. This semi-set engagement ring invites your choice of an 8 x 6 mm emerald-cut diamond, its elongated shape lending a refined elegance to the hand.

Crafted from cool 18K white gold, the split shank gently embraces the finger with a delicate balance of strength and grace. The accented shoulders add subtle sparkle without overwhelming the center, while the low-profile setting ensures everyday comfort and ease beneath gloves or sleeves. Each ring is meticulously finished by hand in our Williamsburg studio, where precision meets quiet artistry.

Our commitment to lab-grown diamonds means your ring carries a clarity and brilliance born from sustainable innovation, reflecting a modern approach to ethical jewelry.

Designed for those who appreciate architectural lines and understated romance, this ring suits slender to medium fingers and pairs beautifully with stackable bands or a simple wedding band. The semi-set format allows you to select a center stone that resonates personally, making the design uniquely yours.

Resizing is available to ensure a perfect fit, and our Brooklyn studio offers a pressure-free experience to explore custom options or view samples in person.
