Lab-Grown Diamond Engagement Ring

Under the soft glow of a Brooklyn sunset, the elongated marquise diamond catches the eye—its tapered points drawing the gaze along a delicate arc of light. This 6 x 3 mm gem, nestled within a halo of finely set pavé stones, amplifies its subtle drama without overwhelming the hand.

Crafted in cool platinum, the ring’s low-profile halo setting balances brilliance with everyday wearability, while the comfort-fit band ensures a gentle embrace on the finger. Each facet is meticulously polished in our Williamsburg studio, where precision meets quiet artistry.

Our lab-grown diamond offers the clarity and fire of natural stones with a fraction of the environmental impact, reflecting a commitment to ethical jewelry without compromise.

Designed for those who appreciate refined romance, this ring complements slender fingers and pairs gracefully with stacking bands or a wedding band of your choice. Its streamlined silhouette slips easily beneath gloves or sleeves, making it a versatile companion for daily life.

Should you need a custom fit, resizing is handled expertly in-house to maintain the integrity of the setting and comfort.
