Lab-Grown Diamond Engagement Ring

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

Handcrafted in warm 10K rose gold, the band is shaped and polished in our Williamsburg studio, where each curve is refined for a comfortable, everyday fit. The three-stone setting balances classic elegance with artisanal detail, securing side stones that frame the center with quiet sophistication. Its low-profile design ensures ease of wear, slipping smoothly beneath gloves or stacking effortlessly alongside other bands.

Each diamond you choose is lab-grown, offering clarity and brilliance with a significantly reduced environmental footprint—an ethical choice that aligns with mindful craftsmanship.

This ring suits those who appreciate a blend of modern geometry and vintage-inspired warmth, perfect for hands that favor slender, elongated shapes. The semi-set format allows you to personalize the centerpiece, making it uniquely yours.

Should you need resizing or guidance on stone selection, our Brooklyn studio offers expert advice and attentive care throughout the process.
