Luna Pear Lab Grown Diamond Curved Engagement Ring
The Luna Pear Lab Grown Diamond Curved Engagement Ring is a modern expression of love, designed with a graceful flowing band that gently embraces a brilliant pear-shaped lab grown diamond.
The pear diamond is positioned in a contemporary east-west orientation, creating a distinctive silhouette that feels elegant, artistic, and beautifully balanced. Its sculptural curved setting follows the natural contour of the finger while allowing the diamond to remain the focal point.
The center stone is available with an IGI certificate, providing verified details of the diamond’s carat weight, color, clarity, and laboratory-grown origin. Each diamond is carefully selected by Sphere Diamond for brilliance, proportion, and visual beauty.
