Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a 6.5 mm round diamond, its facets whispering quiet brilliance between two smaller stones. This three-stone semi-set ring, crafted in warm 18K yellow gold, invites you to imagine the final sparkle yet to come.

Each band is hand-shaped in our Williamsburg studio, polished to a soft glow that complements the diamond’s fire without overwhelming it. The low-profile setting ensures the ring sits comfortably for daily wear, while the semi-set design offers the freedom to select a center stone that reflects your unique story.

Our diamonds are lab-grown with clarity and sustainability in mind, reducing environmental impact without compromising on radiance. The 18K yellow gold band is both durable and inviting, its smooth interior contour designed for a comfort fit that feels like a second skin.

This ring suits those who appreciate artisanal craftsmanship paired with a classic silhouette, perfect for stacking or wearing solo. Its modest height makes it glove-friendly and ideal for an active lifestyle.

Should you need resizing, our Brooklyn studio offers personalized adjustments to ensure a flawless fit. Typical lead times reflect our commitment to careful hand-finishing and quality inspection.
