Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 15 x 15 mm cushion diamond, its halo setting poised to amplify every flicker of light. This semi-set engagement ring foundation invites your choice of a lab-grown center stone, framed by a delicate halo that balances vintage warmth with modern precision.

Crafted from 18K palladium white gold, the band offers a subtle coolness beneath the finger, its surface hand-finished to a smooth, satiny sheen that resists everyday wear. The low-profile halo setting ensures the ring sits comfortably close to the hand, ideal for those who favor understated elegance without sacrificing sparkle.

Each piece reflects a commitment to ethical jewelry: the lab-grown diamond option reduces environmental impact while maintaining exceptional clarity and brilliance. The palladium alloy’s natural strength supports daily wear, making this ring a lasting symbol designed for life’s moments.

Its balanced proportions suit a variety of hand shapes, especially elongating shorter fingers with the cushion’s soft geometry. The halo’s gentle circle complements stacking with wedding bands or accent rings, while the comfort fit band eases all-day wear.
