Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate sparkle that seems to stretch beyond the fingertips. This semi-set engagement ring invites you to choose a 9 x 4.5 mm marquise stone, whose tapered points create a graceful, almost poetic drama.

Crafted in warm 10K rose gold, the slender band is designed with a low-profile solitaire setting that embraces the stone securely while maintaining a refined silhouette. The smooth finish and subtle curvature ensure a comfortable fit for everyday wear, while the rose gold’s gentle glow complements the diamond’s brilliance without overwhelming it.

Each piece reflects our commitment to ethical jewelry: the marquise diamond is lab-grown, offering clarity and sparkle with a lighter environmental footprint. This choice aligns with a modern sensibility rooted in sustainability and mindful luxury.

Ideal for those who appreciate a ring that feels intimate and personal, the slender band pairs effortlessly with wedding bands or stackable rings. Its low profile makes it glove-friendly and unobtrusive, perfect for hands that move through daily life with quiet elegance.

Should you wish to adjust the band size, resizing is handled delicately in our Williamsburg studio to preserve the ring’s integrity and finish. Typical lead times allow for thoughtful customization without rush.
