Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a subtle, tapered glow that draws the eye along the finger’s natural line. This semi-set halo engagement ring foundation in 18K white gold is crafted to balance architectural elegance with everyday resilience.

The low-profile setting ensures the halo gently embraces the 7 x 3.5 mm marquise center without rising too far above the finger, offering a secure yet unobtrusive silhouette. Each curve and prong is meticulously finished in our Williamsburg studio, polished to a smooth comfort fit that wears seamlessly from morning coffee to evening plans.

Our commitment to ethical jewelry is reflected in the lab-grown diamond clarity, providing brilliance with a reduced environmental footprint. This ring’s design suits those who appreciate refined geometry and a piece that layers well with wedding bands or stackable rings.

Resizing is straightforward and handled in-house, ensuring your ring maintains its structural integrity and finish. Whether paired with a delicate band or worn solo, this halo mounting adapts gracefully to various hand shapes and lifestyles.
