Lab-Grown Diamond Engagement Ring

Light catches the elongated points of the marquise diamond, casting a subtle, confident silhouette across the hand. This three-stone semi-set ring in 14K rose gold frames a 9 x 4.5 mm marquise center, its sleek shape lending architectural grace with a modern-minimal edge.

Each band is meticulously crafted in Williamsburg, Brooklyn, with a low-profile setting that balances presence and everyday comfort. The rose gold’s warm glow complements the diamond’s sharp geometry, while the three-stone layout offers a refined narrative of past, present, and future. Finished by hand and inspected for precision, the mounting awaits your choice of center stone to complete this bespoke design.

Our lab-grown diamonds provide a clear, sustainable alternative, reflecting a commitment to ethical jewelry without compromise. The slender band fits comfortably beneath gloves and pairs effortlessly with stacking rings, ideal for those who appreciate subtle structure and clarity in their daily wear.

Resizing is available to ensure a seamless fit, and the semi-set design allows you to select a diamond that speaks personally to your story. Typical lead times reflect our careful handcrafting process, ensuring each piece is made to last.
