Lab-Grown Diamond Engagement Ring

When light catches the elongated marquise diamond at the heart of this ring, it casts a slender, dramatic sparkle that draws the eye along the finger’s natural line. The 9 by 4.5 mm center stone is framed by a delicate halo of smaller diamonds, enhancing its tapered silhouette without adding bulk.

Crafted in cool, enduring platinum, the setting is engineered for everyday wear with a low-profile halo that sits close to the finger, minimizing snagging. The band’s smooth finish and balanced weight offer a comfort fit that feels as natural as it looks refined. Each facet is precisely cut and inspected in our Williamsburg studio to ensure clarity and brilliance.

Choosing a lab-grown diamond means embracing a more sustainable approach to fine jewelry, with the same optical and structural integrity as mined stones but a lighter environmental footprint.

This ring suits someone who values architectural elegance paired with practical design—ideal for those who want a statement piece that integrates seamlessly with daily life and stacks well with wedding bands or delicate bracelets.

Should you need a custom adjustment, resizing is available to ensure a perfect fit without compromising the ring’s profile or balance.
