Lab-Grown Diamond Engagement Ring

Soft corners and gentle curves meet a modern silhouette in this semi-set cushion engagement ring, designed to frame a 6 x 6 mm center stone with quiet confidence. The 10K rose gold band offers a warm, subtle glow that complements the cushion’s vintage-inspired shape without overwhelming it.

Crafted in Williamsburg, the band is polished to a satin finish that feels smooth against the skin, with delicate accent settings ready to enhance your chosen diamond’s clarity and fire. Its low-profile design ensures everyday comfort, slipping easily beneath gloves or alongside other stackable bands.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that reduce environmental impact while maintaining exceptional brilliance and purity. The semi-set style invites you to select a center stone that resonates personally, making the ring uniquely yours.

Ideal for those who appreciate structured elegance with a touch of warmth, this ring suits a variety of hand shapes and sizes, especially those who favor a balance of modern minimalism and classic form. Resizing is available to ensure a perfect fit without compromising the band’s sleek lines.
