Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a hand, where a marquise-shaped diamond stretches gracefully, catching light with a pointed brilliance that feels both bold and refined. This semi-set solitaire ring offers a sleek foundation in 14K rose gold, designed to cradle a 12 x 6 mm marquise center stone with precision and quiet strength.

Crafted in Williamsburg, the band’s low-profile silhouette ensures it sits close to the finger, minimizing snagging and maximizing comfort for everyday wear. The rose gold’s warm glow complements the diamond’s fiery facets, while the setting’s engineering balances security with elegance, allowing light to dance freely through the stone.

Each piece reflects our commitment to ethical jewelry: the center stone is lab-grown, reducing environmental impact without compromising on clarity or fire. This ring suits those who appreciate architectural lines and a confident yet understated presence on the hand.

Its slender band fits seamlessly alongside other rings or stands alone, ideal for stacking or wearing solo. Resizing is available to ensure a perfect fit, crafted with care in our Brooklyn studio.
