Lab-Grown Diamond Engagement Ring

Sunlight catches the soft curves of a 7 x 7 mm cushion diamond, its gentle facets whispering quiet romance. This semi-set solitaire ring offers a poised foundation, inviting your choice of a lab-grown center that balances vintage warmth with modern clarity.

Crafted in 18K white gold, the band’s subtle sheen complements the stone’s rounded edges while maintaining a low-profile setting that rests comfortably against the finger. The smooth finish and precise prong work ensure daily wearability without catching or discomfort.

Each lab-grown diamond reflects a commitment to ethical sourcing and sustainability, embodying a mindful approach to fine jewelry without compromise on brilliance or character.

Designed for those who appreciate understated elegance, this solitaire’s clean lines and moderate size suit slender to medium fingers, pairing effortlessly with wedding bands or stackable rings. Its comfort fit and modest height make it glove-friendly and ideal for everyday life.
