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 Oval Marquise Fan Shoulder Lab Grown Diamond Engagement Ring 1.30ctw combines natural elegance with a distinctive botanical design. Featuring a stunning 1.00-carat oval-cut lab grown center diamond beautifully complemented by 6 marquise-cut lab grown diamonds totaling 0.30 carats arranged in radiating fan clusters of three per shoulder, for an impressive 1.30 total carat weight.
The oval lab grown center diamond delivers exceptional sparkle and an elongating visual effect on the finger, while the marquise shoulder fans radiate outward in a staggered wing-like arrangement that adds dimension and movement to the setting. The plain high-polish comfort-fit shank keeps the focus entirely on the diamond composition above.
