Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it creates a striking interplay of brilliance and shadow that draws the eye along the finger’s natural line. This semi-set engagement ring foundation, crafted in 14K white gold, offers a sleek, low-profile setting designed to showcase a 10 x 5 mm marquise center stone with subtle accent details that enhance its refined geometry.

The band’s smooth finish and secure prong structure ensure daily wearability without catching, while the comfort fit gently embraces the hand for effortless all-day grace. Each piece is meticulously inspected in our Williamsburg studio, where precision meets thoughtful design to balance durability with elegance.

Choosing a lab-grown diamond for this setting reflects a commitment to ethical jewelry, reducing environmental impact without compromising on clarity or fire. The slender profile suits those who prefer a ring that layers seamlessly with wedding bands or stackable styles, and its shape naturally elongates the finger for a flattering silhouette.

Should you wish to adjust sizing, our in-studio experts provide careful resizing to maintain the ring’s structural integrity and finish. Whether you visit us in Brooklyn or design online, this semi-set offers a versatile canvas for your ideal marquise engagement ring.
