Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise diamond, its tapered points drawing the eye along a delicate halo of shimmering pavé. This 10 x 5 mm centerpiece rests securely in a 14K rose gold setting, where the warm blush metal complements the stone’s fiery brilliance without overwhelming it.

Crafted with a low-profile halo design, the ring balances elegance with everyday practicality. The band’s smooth finish and subtle curvature ensure a comfortable fit that slides easily beneath gloves or rings stacked alongside it. Each facet is polished and inspected in our Williamsburg studio, where precision meets quiet durability.

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

Ideal for those who appreciate refined geometry and a ring that wears effortlessly from morning coffee to evening gatherings, this halo setting enhances the marquise’s signature drama while maintaining a sleek silhouette.

Should you need resizing, our in-house artisans provide careful adjustments to maintain the ring’s integrity and comfort.
