Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a cushion-cut diamond, its gentle glow framed by two smaller stones that echo its warmth. This three-stone semi-set ring in 18K yellow gold offers a handcrafted foundation ready to cradle an 8 x 8 mm center gem, inviting your choice to complete its story.

Each band is meticulously shaped and polished in our Williamsburg studio, the warm gold surface smooth to the touch with a subtle comfort fit that sits low against the finger. The three-stone setting balances presence with wearability, designed for everyday elegance without catching or bulk.

Our diamonds are lab-grown, offering clarity and brilliance with a reduced environmental footprint—an ethical choice that aligns with mindful craftsmanship.

This ring suits those who appreciate a classic silhouette with a modern artisan’s touch, ideal for stacking or wearing solo. Its low profile and balanced weight make it glove-friendly and comfortable for daily wear.

Should you need resizing, our in-house jewelers ensure a precise fit without compromising the ring’s integrity or finish.
