Lab-Grown Diamond Engagement Ring

When light catches the elongated curves of a marquise diamond, it creates a silhouette that feels both bold and intimate—like a whispered promise. This semi-set engagement ring offers a poised foundation in 18K white gold, designed to cradle a 12 x 6 mm marquise stone with a low-profile setting that sits close to the finger.

Each band is meticulously crafted in our Williamsburg studio, finished with a smooth comfort fit that invites daily wear without interruption. The slender shank balances strength and grace, allowing the diamond’s signature pointed ends to command attention without overwhelming the hand.

Our commitment to ethical jewelry shines through the choice of a lab-grown diamond, offering clarity and brilliance with a smaller environmental footprint. This ring’s refined silhouette suits those who appreciate modern romance with a subtle edge—ideal for stacking or wearing solo, and glove-friendly for everyday life.

Should you wish to adjust the fit, resizing is handled expertly in-house to maintain the band’s seamless profile. Lead times are tailored to your design journey, ensuring a thoughtful, pressure-free experience.
