Lab-Grown Diamond Engagement Ring

Slender and luminous, the marquise shape stretches light across the finger with a subtle, tapered elegance that feels both intimate and striking. This three-stone semi-set in warm 18K rose gold frames the center diamond’s 6 x 3.5 mm length with two delicate side stones, inviting a personal choice to complete its poetic silhouette.

Crafted in Williamsburg, the band’s gentle curve and polished finish ensure a comfortable fit for everyday wear, while the semi-set design offers flexibility to select a lab-grown diamond that reflects your unique vision. The low-profile setting keeps the ring close to the hand, ideal for stacking or pairing with a wedding band without interruption.

Each piece embodies a commitment to ethical jewelry, featuring lab-grown diamonds that mirror the brilliance of mined stones with a smaller environmental footprint. The rose gold’s soft blush complements the marquise’s vintage-inspired shape, enhancing its romantic warmth.

Designed for those who appreciate subtle drama and refined craftsmanship, this ring suits slender to medium fingers, elongating the hand with its graceful form. Its semi-set nature allows for customization, making it a meaningful foundation for your engagement story.
