Lab-Grown Diamond Engagement Ring

When light catches the elongated marquise center, it casts a slender, dramatic silhouette that subtly elongates the finger. This 7 x 3.5 mm lab-grown diamond is nestled within a delicate halo of pavé stones, enhancing its fiery brilliance without adding bulk.

Crafted in warm 14K rose gold, the ring’s low-profile setting ensures it sits close to the hand, offering comfort for daily wear and ease beneath gloves or sleeves. Each facet is meticulously polished, and the halo’s micro-prong setting secures every stone with precision, reflecting the quiet expertise of our Williamsburg studio.

Our diamonds are sustainably grown, embodying clarity and conscience in equal measure.

The slender band complements a variety of hand shapes, especially those who appreciate a refined, stackable silhouette that balances statement with subtlety.

Should you need a custom fit, resizing is straightforward and handled in-house with care.
