Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This semi-set halo engagement ring in 18K white gold offers a refined stage for a 7 x 3.5 mm marquise center, designed to balance presence with everyday ease.

Crafted with a low-profile halo setting, the band sits close to the finger, reducing snag risk while maintaining a graceful sparkle. The cool white gold is polished to a smooth finish, complementing the diamond’s sharp geometry without overwhelming it. Each mounting is meticulously inspected in our Williamsburg studio to ensure comfort fit and lasting wearability.

Our diamonds are lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising brilliance or clarity.

This ring suits those who appreciate architectural elegance paired with practical design—its slim profile fits comfortably beneath gloves and stacks seamlessly with other bands. The marquise shape’s elongation enhances the hand’s natural lines, making it a striking choice for slender or average finger sizes.

Should you wish to customize the center stone or explore sizing options, our Brooklyn studio offers personalized consultations with attentive care and transparent timelines.
