Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This semi-set halo engagement ring in 14K yellow gold frames a 9 x 4.5 mm marquise center stone, offering a refined balance between presence and practicality.

Crafted with a low-profile halo setting, the ring sits close to the hand, minimizing snagging while maximizing daily comfort. The warm glow of 14K yellow gold complements the marquise’s graceful shape, a design choice that enhances both durability and wearability. Each piece is meticulously finished and inspected in our Williamsburg studio to ensure a seamless fit and lasting polish.

Our lab-grown diamonds provide a clear, sustainable alternative, reflecting a commitment to ethical jewelry without compromise on brilliance or clarity.

Ideal for those who appreciate architectural elegance paired with everyday ease, this ring’s slender profile and secure halo setting make it glove-friendly and stackable with complementary bands. The marquise shape visually elongates the finger, lending a distinctive yet understated statement.

Resizing is available to ensure a perfect fit, with typical lead times tailored to your custom design preferences.
