Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, its tapered points drawing the eye along a graceful, almost architectural line. This semi-set solitaire mounting awaits your choice of a 9 x 4.5 mm center stone, designed to showcase the marquise’s distinctive drama without overwhelming the hand.

Crafted from 14K white gold, this setting balances subtle strength with refined elegance. The low-profile design keeps the diamond close to the finger, minimizing snagging while maximizing comfort for everyday wear. Each curve and prong is meticulously finished in our Williamsburg studio, ensuring a secure hold and smooth feel against the skin.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, offering clarity and brilliance with a smaller environmental footprint. This setting’s streamlined silhouette suits those who appreciate modern geometry and a confident, understated presence.

Ideal for slender to medium finger sizes, the marquise shape visually elongates the hand, while the solitaire style stands beautifully alone or layered with stackable bands. Its glove-friendly profile and comfort fit make it a practical choice for daily life.

Should you need resizing, our in-house artisans handle adjustments with care, preserving the integrity of the setting without delay.
