Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a large cushion diamond, its gentle glow framed by two smaller stones that echo its vintage charm. This three-stone semi-set ring features an 18K yellow gold band, hand-shaped and polished in our Williamsburg studio to a warm, buttery finish that feels substantial yet comfortable on the finger.

The setting is designed with a low profile to sit close to the hand, allowing daily wear without catching. Each prong is carefully tapered to secure the stones while maintaining an open view of their faceted surfaces, enhancing the cushion’s subtle sparkle and depth. The band’s smooth interior offers a comfort fit, ideal for those who prefer a ring that moves naturally with the hand.

Our diamonds are lab-grown, offering the clarity and fire of mined stones with a significantly reduced environmental footprint. This ring’s ethical foundation aligns with a mindful approach to fine jewelry, crafted for a lifetime of moments.

Its generous 11 x 11 mm cushion center stone lends a soft, vintage glow that complements a variety of hand shapes, especially elongating shorter fingers with its balanced proportions. The three-stone design invites stacking with wedding bands or accent rings, making it versatile for evolving personal styles.

Should you wish to adjust the fit, resizing is available through our in-studio service, ensuring the ring maintains its structural integrity and finish.
