Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate sparkle that dances along the gentle curve of a 14K rose gold band. This engagement ring, set with a 9 by 4.5 mm marquise center stone, balances bold geometry with a soft, warm glow.

Handcrafted in our Williamsburg studio, the ring features artisan detailing with subtle accent stones that frame the center diamond, enhancing its tapered drama without overwhelming its refined profile. The low-set mounting ensures everyday comfort, while the smooth, polished band feels light and secure on the finger.

Each lab-grown diamond is selected for clarity and brilliance, reflecting a commitment to sustainable, ethical jewelry that honors both craftsmanship and conscience.

Designed for those who appreciate distinctive shapes and understated elegance, this ring complements slender fingers and pairs effortlessly with stacking bands or a wedding band. Its low profile makes it glove-friendly and ideal for daily wear.

Should you need a custom fit, resizing is available to ensure the ring sits perfectly.
