Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise diamond, casting a slender, dramatic silhouette across the hand. This three-stone engagement ring centers on an 8 x 4 mm marquise cut, its sharp geometry softened by the gentle curve of the 14K white gold band.

Each diamond is securely nestled in a low-profile setting, crafted with precision in our Williamsburg studio to ensure daily wearability without catching or discomfort. The smooth comfort-fit shank balances the ring’s architectural presence with a subtle tactile ease, finished to a mirror polish that enhances the cool glow of white gold.

Our commitment to ethical jewelry is reflected in the lab-grown diamonds, offering clarity and brilliance with a significantly reduced environmental footprint.

This ring suits those who appreciate a bold yet refined statement—its tapered shape elongates the finger gracefully, while the three-stone design adds depth and meaning. Its modest height and secure setting make it ideal for stacking or wearing alongside a wedding band.

Resizing is available to ensure a precise fit, crafted carefully by hand to maintain the ring’s structural integrity.
