Lab-Grown Diamond Engagement Ring

Light catches the soft, rounded corners of a 12 x 12 mm cushion diamond, its gentle glow unfolding like a quiet breath. This semi-set solitaire ring in 18K white gold offers a refined foundation, designed to cradle your chosen stone with precision and subtlety.

Crafted with a low-profile setting, the band sits close to the finger, balancing presence with everyday comfort. The cool white gold is polished to a smooth finish, ensuring a seamless feel beneath the hand. Each mounting undergoes meticulous inspection in our Williamsburg studio, where expert jewelers shape and refine every curve for lasting wearability.

Our commitment to ethical jewelry is reflected in the choice of lab-grown diamonds, combining clarity and sustainability without compromise.

The ring’s streamlined silhouette suits those who prefer a modern solitaire with a discreet profile—ideal for stacking or wearing solo. Its comfort fit accommodates daily life, slipping easily under gloves or alongside other bands.

Should you need resizing, our Brooklyn studio offers personalized adjustments to ensure the perfect fit without disrupting the ring’s clean lines.
