Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set three-stone engagement ring foundation in 14K white gold invites your choice of a 10 x 5 mm center stone, ready to become a personal statement of refined geometry and quiet drama.

Handcrafted in our Williamsburg studio, the band is meticulously shaped for a smooth, comfort fit that rests lightly against the finger. The three-stone setting balances presence with wearability, designed to sit low enough for everyday ease while allowing light to dance through the marquise’s distinctive facets. Each prong is carefully finished to secure your center stone without overwhelming its slender form.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, offering clarity and brilliance with a smaller environmental footprint. This ring’s profile suits those who appreciate architectural elegance paired with practical design—ideal for stacking with a wedding band or worn solo as a statement of modern romance.
