Lab-Grown Diamond Engagement Ring

Imagine the quiet confidence of a square diamond catching the light with crisp, architectural precision—each facet a subtle flash of clarity. This semi-set solitaire ring offers a refined foundation crafted from 10K white gold, designed to cradle a 4 x 4 mm square center stone with a low-profile setting that stays close to the finger.

The band’s smooth finish and balanced weight ensure comfort for everyday wear, while the secure prong arrangement allows the diamond’s geometry to command attention without excess height. Expertly shaped and polished in our Williamsburg studio, this mounting reflects a commitment to precision and durability.

Choosing a lab-grown diamond here means embracing a cleaner origin story, reducing environmental impact without compromising brilliance or integrity.

Its streamlined silhouette suits those who favor subtle sophistication—ideal for stacking with other bands or wearing solo with ease, even under gloves or daily tasks. The square shape’s modern edge complements a variety of hand shapes, lending a contemporary yet understated presence.

Should you need resizing, our in-house artisans handle adjustments with care to maintain the ring’s structural harmony. Typical lead times for setting your chosen stone are communicated clearly during consultation.
