Lab-Grown Diamond Engagement Ring

Imagine the moment sunlight catches a marquise diamond’s tapered points, casting a delicate dance of light across your hand. This three-stone semi-set engagement ring in platinum frames a 9 x 4.5 mm marquise center with two gently flanking stones, creating a silhouette that feels both intimate and expansive.

Crafted in our Williamsburg studio, the ring’s low-profile setting ensures a comfortable fit beneath daily wear, while the polished platinum band offers subtle weight and cool smoothness against the skin. Each prong is meticulously finished to cradle the elongated marquise securely, highlighting its signature pointed elegance without overwhelming the hand.

Our commitment to sustainability is reflected in the lab-grown diamond’s clarity and brilliance—ethically sourced with a fraction of the environmental impact compared to mined stones.

Designed for those who appreciate refined romance, this ring complements slender fingers and pairs beautifully with stackable bands or a simple wedding band. Its modest height makes it glove-friendly and ideal for everyday life.

Should you wish to adjust the fit, resizing is available with care to preserve the ring’s structural integrity and finish.
