Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a 6 mm round diamond, waiting to be chosen and set in a three-stone embrace. This semi-set ring foundation, crafted from warm 18K yellow gold, offers a tactile richness with its hand-finished shank, shaped for everyday comfort and subtle elegance.

The three-stone design balances presence and grace, its low-profile setting ensuring the ring sits close to the finger, ideal for stacking or wearing solo. Each curve and angle is refined in our Williamsburg studio, where artisan hands polish and inspect every detail to a quiet brilliance.

Our commitment to lab-grown diamonds means your center stone will reflect clarity and light with a smaller environmental footprint, aligning with a modern ethos of ethical jewelry.

Designed for those who appreciate craftsmanship and understated luxury, this ring foundation suits a variety of diamond cuts but especially highlights the classic round shape’s lively sparkle and timeless geometry.

Should you need resizing or custom adjustments, our Brooklyn studio offers personalized consultations to ensure a perfect fit and finish.
