Quick Tips
- Measure at the end of the day, when fingers are largest.
- Snug, not tight — the ring should pass your knuckle with slight resistance.
- Wider bands (4mm+) fit tighter — consider sizing up half a size.
- Between two sizes? Always size up.

Our Half Eternity Shared Prong Lab Grown Diamond Wedding Band is the perfect complement to any engagement ring or a standalone celebration of every day. A continuous row of round lab grown diamonds, totalling 0.50ctw, is set in delicate shared bead prongs that run across the top half of the band, each stone catching the light with effortless brilliance. The bottom half remains a smooth, plain polished arc — a thoughtful design choice that ensures comfortable wear while keeping the profile sleek and refined.
The shared bead-prong setting places each pair of lab grown diamonds in intimate proximity, with shared metal beads holding them side by side in a seamless row that flows from shoulder to shoulder. The slender band width lets the lab grown diamonds take centre stage without adding bulk — a ring that layers beautifully with an engagement ring or stands confidently on its own as an anniversary or milestone band.
Available in 10K/14K/18K White, Yellow, or Rose Gold and Platinum.
