Lab-Grown Diamond Engagement Ring

Imagine the delicate silhouette of a marquise diamond catching the soft morning light, its tapered points drawing the eye along the graceful curve of your finger. This semi-set solitaire ring offers a refined foundation in 14K white gold, its cool sheen a quiet contrast to the warm blush of rose gold accents, ready to cradle a 7 x 3.5 mm marquise stone of your choosing.

Handcrafted in Williamsburg, the band is polished to a satin finish that feels smooth beneath the hand, designed with a low-profile setting to sit comfortably for everyday wear. The slender shank balances strength with subtlety, allowing the diamond’s elongated shape to appear even more striking without overwhelming the finger.

Each lab-grown diamond we select embodies clarity and brilliance while reflecting a commitment to sustainable sourcing, minimizing environmental impact without compromising on beauty.

This ring suits those who appreciate a blend of classic romance and modern craftsmanship—its slender form ideal for stacking or wearing solo, and its gentle curve accommodating a variety of hand shapes with ease.

Should you wish to adjust the fit, resizing is available to ensure the ring feels as natural as it looks.
