Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a 12 mm round diamond, waiting to become the heart of a three-stone engagement ring. This semi-set foundation, crafted from 10K white gold, offers a sleek, low-profile band that balances strength with subtlety, designed to showcase your chosen center stone with clarity and grace.

Each band is hand-finished in our Williamsburg studio, where artisans refine the smooth comfort fit and secure prong settings that cradle side stones with precision. The cool sheen of white gold complements the diamond’s brilliance, while the three-stone layout invites a narrative of past, present, and future.

Our commitment to lab-grown diamonds ensures an ethical origin with exceptional clarity, reducing environmental impact without compromising on radiance.

Ideal for those who appreciate a refined silhouette that wears comfortably every day, this ring’s low profile slips easily beneath gloves and stacks effortlessly with wedding bands or accent rings.
