Lab-Grown Diamond Engagement Ring

When light catches the elongated points of this marquise diamond, it carves a striking silhouette that feels both bold and refined. The 9 x 4.5 mm center stone is embraced by a delicate halo, amplifying its tapered drama without adding bulk.

Crafted in cool platinum, the ring features a low-profile setting designed for everyday wear. Its secure prongs and smooth comfort-fit band ensure the ring sits close to the finger, minimizing snagging and maximizing ease of movement. Each piece is meticulously finished and inspected in our Williamsburg studio, reflecting a commitment to precision and durability.

Our marquise diamond is lab-grown, offering a clarity and brilliance that aligns with sustainable values without compromise.

This engagement ring suits those who appreciate architectural elegance paired with practical design—ideal for hands that favor a slender, elongated shape or for stacking alongside complementary bands. Its streamlined silhouette fits comfortably under gloves and daily wear.

Should you need resizing, our in-house artisans adjust the band with care to maintain its integrity and balance.
