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 Round Chevron Gallery Lab Grown Diamond Engagement Ring is built around one of the most commanding center stones in fine jewellery: a breathtaking 6.90ctw round lab grown center diamond that commands every room it enters. Four round bead prongs hold the stone in a setting defined by its striking chevron gallery — a bold V-shaped arrow cutout beneath the lab grown diamond that draws the eye upward toward the stone's incomparable brilliance, while allowing maximum light to flood the pavilion from below.
The knife-edge ridge shank is the architectural counterpart to this exceptional stone. A sharp, raised central ridge runs the full length of the band, tapering to a crisp apex that gives the ring a dramatic, angular profile unlike any rounded comfort shank. Viewed from above, the ridge creates a clean converging line that draws the eye directly to the lab grown diamond — a design choice that is as intentional as it is striking.
Available in 10K/14K/18K White, Yellow, or Rose Gold and Platinum.
