Lab-Grown Diamond Engagement Ring

Imagine the soft glow of a 7 x 7 mm cushion-cut diamond poised to catch the light with every movement—its gentle curves offering a quiet yet confident presence. This semi-set solitaire ring foundation in 18K rose gold invites your choice of center stone, framed by a delicately tapered band finished in warm rose tones for subtle contrast.

Crafted with a low-profile setting, the mounting ensures the ring sits close to the finger, enhancing comfort and everyday wearability without sacrificing elegance. The band’s smooth polish and precise finishing reflect careful inspection typical of our Williamsburg studio’s standards.

Each piece embraces lab-grown clarity, aligning with a commitment to sustainable, ethical jewelry that respects both the earth and your values.

Designed for those who appreciate understated sophistication, this solitaire mounting suits a variety of hand shapes and sizes, offering a versatile base for stacking or solo wear. Its modest height makes it glove-friendly and ideal for daily life.

Should you need resizing, our in-house artisans handle adjustments with care to maintain the ring’s integrity and balance.
