Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 5x5 mm cushion diamond, its gentle glow framed by two smaller stones that balance modern minimalism with quiet structure. This semi-set three-stone ring in 18K white gold offers a refined silhouette, where clean lines meet subtle brilliance.

Crafted in Williamsburg, Brooklyn, the band’s low-profile setting ensures a comfortable fit for daily wear, while the polished finish reflects light with a cool, architectural clarity. Each prong is meticulously shaped to cradle your chosen center stone securely, marrying form and function with a confident restraint.

Our commitment to ethical jewelry is reflected in the lab-grown diamond’s clarity and sustainability, offering a conscious alternative without compromise. The design’s streamlined shape suits those who appreciate modern geometry and desire a ring that layers effortlessly with other bands or stands alone with quiet distinction.

Should you need resizing, our in-studio experts handle adjustments with care to maintain the ring’s sleek proportions. Lead times are transparent and tailored to your custom design journey.
