Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a slender finger, crowned by a marquise diamond that catches light with a graceful, tapered brilliance. This semi-set solitaire invites you to select a center stone measuring 9 by 4.5 millimeters, its distinctive shape evoking a refined drama balanced by delicate artistry.

Crafted in warm 14K rose gold, the mounting features a slender band with a low-profile setting that nestles comfortably against the hand. Each prong is meticulously shaped and polished in our Williamsburg studio, ensuring the ring’s silhouette remains elegant yet durable for everyday wear.

Our commitment to sustainability shines through the choice of lab-grown diamonds, offering clarity and sparkle without compromise. This ethical approach aligns with a modern sensibility rooted in responsible craftsmanship.

The slender band suits those who appreciate a ring that feels light and natural, ideal for stacking or wearing solo. Its low profile makes it glove-friendly and unobtrusive, perfect for daily life in Brooklyn’s vibrant rhythm.

Should you wish to adjust the fit, resizing is available with care to preserve the ring’s refined lines. Lead times reflect our artisan process, ensuring each piece meets exacting standards.
