Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow that seems to dance with every movement. This semi-set solitaire invites you to choose a center stone that will become a personal beacon of light.

Crafted in warm 10K rose gold, the band is gently tapered to complement the marquise’s graceful points without overwhelming its delicate shape. The setting’s low profile ensures the ring sits close to the finger, offering both comfort and subtlety for everyday wear. Each piece is meticulously finished by hand in our Williamsburg studio, where precision meets quiet artistry.

Our diamonds are lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising on brilliance or clarity.

Designed for those who appreciate refined romance, this solitaire suits slender fingers and pairs effortlessly with stacking bands or a wedding ring. Its modest height makes it glove-friendly and ideal for a life in motion.

Should you wish to adjust the fit, resizing is available with care to maintain the integrity of the band’s delicate profile.
