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 Solitaire Lab Grown Diamond Engagement Ring with Shared Prong Shank offers a beautifully balanced combination of geometric precision and classic elegance. A striking 1.25ctw princess-cut lab grown center diamond sits in a 4-prong corner bead cathedral setting, elevated proudly above the band, while a single row of large shared-prong set round lab grown diamonds flows along both shoulders for a bold 1.85 total carat weight.
The princess cut's clean square geometry is perfectly complemented by the round lab grown diamonds on the shank — an intentional contrast of shapes that creates visual interest without competing with the centre stone. The open cathedral gallery beneath the setting is clean and unadorned, allowing the center lab grown diamond's brilliance to take centre stage. The shank lab grown diamonds run the top half of the band only, with a plain polished base for comfort.
Available in 10K/14K/18K White, Yellow, or Rose Gold and Platinum.
