Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic shadow across the hand. This halo setting amplifies that effect, surrounding the 7 x 3.5 mm center stone with a delicate frame of smaller lab-grown diamonds that shimmer like morning dew.

Crafted in cool platinum, the ring’s low-profile halo setting balances bold geometry with everyday wearability. The smooth comfort fit band curves gently beneath the finger, while the artisan finish reveals subtle hand-polished facets that catch light from every angle. Each diamond is meticulously set by hand in our Williamsburg studio, ensuring precision and durability.

Our lab-grown diamonds offer the same optical brilliance and clarity as mined stones, with a significantly reduced environmental footprint.

This engagement ring suits those who appreciate architectural elegance paired with a refined, glove-friendly silhouette. Its slender marquise shape elongates the finger, while the halo adds presence without bulk—ideal for stacking or solo wear.

Should you need a custom size, resizing is available with care to maintain the ring’s structural integrity and finish.
