Lab-Grown Diamond Engagement Ring

Sunlight catches the softly rounded corners of a large cushion diamond, its gentle glow poised to become the centerpiece of a lifelong promise. This semi-set engagement ring frame, crafted in warm 18K rose gold, offers a delicate balance of modern minimalism and structural clarity, designed to highlight an 11 x 11 mm cushion stone of your choosing.

The band’s smooth, polished surface complements the diamond’s subtle vintage-inspired facets, while the low-profile setting ensures everyday comfort and ease of wear. Each curve and angle is meticulously finished in our Williamsburg studio, where precision meets quiet confidence in every detail.

Choosing a lab-grown diamond for this ring aligns with a commitment to ethical sourcing and sustainability, reflecting a modern approach to fine jewelry without compromise.

Its generous size and soft shape suit hands that appreciate bold yet refined statements, while the semi-set design invites personal selection of a center stone that resonates with your story. The ring’s streamlined silhouette pairs effortlessly with stacking bands or stands alone with quiet authority.

Should you need resizing or custom adjustments, our Brooklyn studio offers attentive care to ensure a perfect fit without delay.
