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 elegantly stretches the finger. This semi-set engagement ring features a 6 x 3.5 mm marquise center designed to showcase the stone’s tapered drama without distraction.

Crafted in warm 18K rose gold, the mounting is engineered for everyday wear with a low-profile setting that sits close to the hand, minimizing snagging. The band’s subtle taper and smooth finish ensure comfort fit, while the prongs are precisely shaped to secure the stone with technical assurance.

Each piece is finished and inspected in our Williamsburg studio, where expert hands refine every detail to balance durability with refined aesthetics. The rose gold’s gentle blush complements the marquise’s fiery facets, creating a harmonious visual flow.

Our commitment to ethical jewelry is reflected in the use of a lab-grown diamond, offering clarity and brilliance with a smaller environmental footprint. This ring suits those who appreciate sculptural elegance and a design that integrates seamlessly into daily life, whether worn solo or stacked with complementary bands.

Should you need adjustments, resizing is handled expertly in-house to maintain the integrity of the setting. Typical lead times are communicated clearly during consultation to ensure a smooth process.
