Lab-Grown Diamond Engagement Ring

Light catches the elongated points of a 6 x 3 mm marquise diamond, casting a subtle, graceful silhouette that elongates the finger with quiet drama. This semi-set halo engagement ring in 14K white gold offers a refined foundation, ready to cradle your chosen center stone with precision and care.

Crafted for everyday wear, the low-profile setting keeps the halo close to the finger, minimizing snagging while maximizing sparkle. The smooth comfort fit band balances durability with ease, designed to move naturally with your hand. Each piece is meticulously finished and inspected in our Williamsburg studio, ensuring a flawless surface and secure prongs.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, combining brilliance with a reduced environmental footprint. This ring suits those who appreciate architectural elegance paired with practical design—ideal for stacking or wearing solo without overwhelming the hand.

Should you need resizing, our Brooklyn studio offers personalized adjustments to ensure a perfect fit without compromising the ring’s integrity. Typical lead times reflect our handcrafted approach, allowing space for thoughtful customization.
