Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curves of a marquise diamond, casting a slender, luminous shadow that dances along the finger. This semi-set solitaire invites you to choose a center stone that embodies your unique story, framed by a warm 14K yellow gold band that feels familiar and effortless.

Crafted in Williamsburg, the band’s gentle arch and smooth finish ensure a comfortable fit for daily wear, while the low-profile setting keeps the diamond close to the hand, ideal for stacking or glove-friendly occasions. Each piece is meticulously shaped and polished in-studio, reflecting a quiet dedication to refined craftsmanship.

Our lab-grown diamonds offer a clarity and brilliance that honors both beauty and sustainability, reducing environmental impact without compromise. The marquise shape, with its tapered points and graceful silhouette, elongates the finger and lends an air of subtle drama without excess.

Designed for those who appreciate understated elegance and a personal touch, this ring adapts seamlessly to varied lifestyles and styles. Resizing is available to ensure your ring fits as naturally as it feels.
