Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, confident silhouette across the hand. This three-stone semi-set ring in 10K white gold frames a 12 x 6 mm marquise center with two delicate side stones, balancing architectural precision with modern minimalism.

Each band is meticulously crafted in Williamsburg, Brooklyn, with a low-profile setting that sits close to the finger for everyday ease. The smooth comfort fit and secure prong work ensure the ring feels as refined as it looks, while the polished finish reflects light subtly without overwhelming the diamond’s sharp geometry.

Our lab-grown diamonds offer a clear, sustainable alternative, grown with care to meet exacting standards of brilliance and ethical responsibility.

This design suits those who appreciate structured elegance and a ring that complements slender fingers or elongates the hand’s natural lines. Its low profile and streamlined shape make it ideal for stacking or wearing solo with ease.

Resizing is straightforward, handled in-studio with attention to preserving the ring’s clean lines and balance.
