Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise shape, its pointed ends drawing the eye along a graceful arc. This semi-set engagement ring in 18K white gold offers a sleek foundation designed to showcase a 9 x 4.5 mm marquise diamond, framed by delicate accent stones that enhance its refined profile.

Crafted with a low-profile setting, the band sits close to the finger, reducing snagging while maintaining a comfortable fit for everyday wear. The cool sheen of 18K white gold is hand-finished in Williamsburg, ensuring a smooth surface and precise prong placement that secures your center stone with subtle strength.

Each diamond is lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising brilliance or clarity. This ring’s streamlined design suits those who appreciate architectural elegance paired with practical durability.

Its slender band and modest height make it ideal for stacking alongside wedding bands or other fine jewelry, while the marquise shape visually elongates the hand, lending a poised yet modern statement. Resizing is available to ensure a perfect fit, crafted carefully in-studio to maintain structural integrity.
