Lab-Grown Diamond Engagement Ring

Soft light catches the gentle curves of a 5 x 5 mm cushion diamond, waiting to become the heart of a three-stone embrace. This semi-set engagement ring in 10K rose gold offers a warm, blushing foundation that complements the stone’s rounded corners and subtle sparkle.

Crafted in Williamsburg, the band’s delicate sweep is polished to a satin finish, balancing everyday wear with refined elegance. The three-stone setting is designed with low-profile prongs that cradle your center diamond securely while maintaining a graceful silhouette that slips easily beneath gloves or sleeves.

Each ring begins with a lab-grown diamond, chosen for its clarity and ethical origin, reflecting a commitment to sustainability without compromise. The rose gold’s gentle hue enhances the diamond’s soft glow, creating a romantic harmony that suits hands seeking both comfort and quiet distinction.

Ideal for those who appreciate a ring that layers beautifully with wedding bands or stackable styles, this setting’s modest height and smooth edges ensure it feels as natural as it looks. Resizing is available to ensure a perfect fit, crafted with care in our Brooklyn studio.
