Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of an oval diamond, its elongated silhouette casting a subtle glow across the hand. This three-stone semi-set invites you to select a 7 x 5 mm oval center, known for its graceful elongation that visually lengthens fingers with a soft, luminous presence.

Crafted from warm 18K yellow gold, the mounting features finely tapered prongs and a low-profile setting that nestles close to the finger, designed for everyday wear without catching. Each band is hand-finished in our Williamsburg studio, polished to a satin-smooth comfort fit that balances artisan detail with modern ease.

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

This ring suits those who appreciate a classic shape with a contemporary twist—its three-stone design adds dimension without bulk, making it ideal for stacking or wearing solo. The low profile ensures it slips easily under gloves or sleeves, perfect for an active lifestyle.

Should you need resizing, our Brooklyn studio provides precise adjustments to ensure a seamless fit without compromising the ring’s integrity.
