Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curves of a marquise diamond, casting a slender, dramatic silhouette across the hand. This 12 x 6 mm marquise center stone is set in a sleek 14K rose gold band, its warm blush hue complementing the gem’s sharp geometry with subtle contrast.

Crafted in Williamsburg, this engagement ring features a modern-minimal design that balances clarity and structure. The low-profile setting secures the diamond with delicate prongs, allowing light to flood the stone’s facets while maintaining everyday wearability. The smooth rose gold band offers a comfortable fit, ideal for those who appreciate refined simplicity with a confident edge.

Each lab-grown diamond is ethically sourced, ensuring brilliance without compromise to the environment. This ring’s design suits hands that favor elongation and elegance, pairing effortlessly with stackable bands or worn solo as a statement of quiet sophistication.

Should you need a custom fit, resizing is available to ensure the ring feels as natural as it looks. Lead times are typically two to three weeks, reflecting the care poured into every detail.
