Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic shadow across the hand. This semi-set engagement ring invites you to select a center stone that measures 12 by 6 millimeters, its pointed ends lending a striking, tapered elegance.

Crafted from warm 18K rose gold, the band is shaped with a subtle comfort fit, its smooth interior designed for daily wear. The solitaire setting is deliberately low-profile, allowing the marquise to appear as if it floats just above the finger, while secure prongs cradle the stone with artisan precision. Each ring is finished by hand in our Williamsburg studio, where careful inspection ensures a refined surface and balanced proportions.

Choosing a lab-grown diamond here means embracing clarity and brilliance without compromise, reflecting a commitment to sustainability and ethical sourcing.

This ring suits those who appreciate bold geometry paired with understated comfort—its slender shape elongates the finger and pairs effortlessly with stacking bands or a wedding band. The low profile also makes it glove-friendly and unobtrusive for everyday life.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure a perfect fit without disrupting the ring’s delicate silhouette.
