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 Princess Double Starburst Halo Lab Grown Diamond Engagement Ring is an extraordinary statement piece for those who demand nothing less. At the heart sits a breathtaking 3.50ctw princess-cut lab grown center diamond delivering an explosion of light and fire, surrounded by a double starburst halo unlike anything in conventional fine jewellery: an inner ring of round lab grown diamonds hugs the girdle of the center stone in a continuous pavé embrace, while an outer ring of individually prong-set marquise lab grown diamonds radiates outward like spokes of a sunburst wheel.
From the side, the true artistry of the setting reveals itself — a towering, architecturally complex halo construction with each marquise stone set at a slight upward angle, creating a dimensional crown effect that is as impressive in profile as it is from above. The multiple prong stems beneath the halo form an intricate open gallery that lets light flood through from below. A plain tapered comfort-fit shank provides an intentionally clean counterpoint to the magnificence of the setting above, ensuring all eyes remain on the center stage.
Available in 10K/14K/18K White, Yellow, or Rose Gold and Platinum.
