Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set three-stone engagement ring invites your choice of a 9 x 4.5 mm lab-grown marquise center, framed by two delicately crafted side stones that echo its refined geometry.

Handcrafted in 18K white gold, the band’s smooth surface is polished to a soft sheen, balancing strength with subtle elegance. The setting’s low profile and secure prongs ensure daily wearability without catching, while the comfort fit band gently embraces the finger, making it ideal for stacking or solo wear.

Each diamond is ethically cultivated, offering clarity and brilliance without compromise to the earth. This ring’s design honors sustainability through lab-grown stones, reflecting a commitment to responsible luxury.

Its slender shape and three-stone arrangement suit hands that appreciate architectural detail with a touch of vintage romance. The marquise’s elongated form visually lengthens the finger, while the balanced side stones add depth and light play.
