Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender shadow that dances with quiet elegance. This semi-set solitaire invites you to choose a center stone that reflects your unique story.

Crafted in 18K white gold, the mounting features a delicate, low-profile setting that cradles the marquise shape with slender prongs, allowing maximum light to pass through the stone’s pointed ends. The band’s smooth finish and subtle taper ensure a comfortable fit for daily wear, while the refined silhouette complements slender and average finger sizes alike.

Each ring is thoughtfully designed in our Williamsburg studio, where lab-grown diamonds offer a clear, sustainable alternative without compromising brilliance or integrity.

The solitaire style suits those who appreciate understated romance and the striking geometry of a marquise cut—its tapered points elongate the hand, lending a graceful, refined presence. This mounting pairs beautifully with stacking bands or worn solo for a statement of quiet confidence.

Should you need resizing, our in-house artisans provide precise adjustments to ensure your ring fits seamlessly.
