Lab-Grown Diamond Engagement Ring

The elongated silhouette of the marquise diamond, measuring 8 by 4 millimeters, creates a striking visual that gently extends the finger with tapered elegance. This semi-set halo engagement ring foundation in 14K white gold offers a low-profile setting designed for everyday wear, balancing refined sparkle with practical comfort.

Crafted in Williamsburg, Brooklyn, the band is smoothly finished with a comfort fit that nestles naturally against the skin, while the halo setting is engineered to enhance the center stone’s brilliance without adding bulk. Each mounting undergoes meticulous inspection to ensure precise prong alignment and durability.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, combining clarity and sustainability without compromise.

This design suits those who appreciate a sleek, architectural shape with a subtle halo that adds dimension without overwhelming the hand. Its streamlined profile fits well under gloves and stacks effortlessly with complementary bands.

Resizing is available to ensure a perfect fit, and the semi-set allows you to select a marquise diamond that meets your exact preferences.
