Lab-Grown Diamond Engagement Ring

Light catches the elongated marquise shape, casting a slender, dramatic silhouette that draws the eye along the finger’s natural line. This three-stone semi-set ring offers a refined foundation for a 7 x 3.5 mm marquise center diamond, framed by two delicate side stones that enhance its architectural grace.

Crafted from 14K white gold, the band is polished to a soft sheen with a subtle comfort fit that rests lightly against the skin. The low-profile setting balances presence with everyday wearability, designed and finished in our Williamsburg studio where each detail is inspected under magnification to ensure precision.

Our commitment to sustainability is reflected in the use of lab-grown diamonds, offering clarity and brilliance with a smaller environmental footprint.

Ideal for those who appreciate a statement ring that remains practical—its slender shape complements slender or average finger sizes and layers beautifully with wedding bands or stackable rings. The semi-set design invites you to select a center stone that resonates personally, making this ring uniquely yours.
