Lab-Grown Diamond Engagement Ring

Sunlight catches the slender silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to elongate the hand with quiet grace. This semi-set halo engagement ring invites you to choose a 6 x 3 mm lab-grown marquise center, framed by a whisper of smaller stones that catch light from every angle.

Crafted in warm 10K yellow gold, the band is polished to a soft glow, its low-profile setting designed for everyday wear without catching or discomfort. Each halo stone is meticulously set by hand in our Williamsburg studio, ensuring a secure embrace that enhances the marquise’s signature brilliance and sculptural form.

Our diamonds are lab-grown, offering exceptional clarity and sparkle with a mindful approach to sustainability and ethical sourcing.

The slender band suits those who appreciate subtle drama and refined elegance, pairing effortlessly with stacking rings or worn solo for a statement that feels personal and intentional. Its comfort fit and modest height make it glove-friendly and ideal for daily life.

Should you wish to adjust the band size, resizing is available with care to preserve the ring’s delicate proportions.
