Lab-Grown Diamond Engagement Ring

Sunlight catches the broad facets of a 12 by 10 mm emerald-cut diamond, casting a glassy, architectural glow that stretches elegantly across the finger. This three-stone semi-set ring invites you to select your own center stone, resting on a finely crafted 14K white gold band shaped for everyday grace.

Each band is meticulously forged in our Williamsburg studio, featuring a low-profile setting that balances presence with comfort. The smooth shank curves gently, designed to sit close to the hand without catching, making it ideal for stacking or wearing solo. Our artisans finish every edge with care, ensuring a tactile experience as refined as the visual.

Choosing a lab-grown diamond here means embracing clarity and sustainability without compromise—ethical jewelry that honors both craftsmanship and conscience.

This ring suits those who appreciate architectural lines and understated drama, especially on medium to larger hands where the emerald shape elongates the finger. Its semi-set design offers flexibility to personalize your engagement with a stone that reflects your unique story.
