Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with quiet drama. This semi-set solitaire ring in 14K yellow gold offers a sleek foundation, ready to cradle a 9 by 4.5 mm lab-grown marquise center stone with precision.

Crafted for everyday grace, the band’s low-profile setting ensures the ring sits close to the hand, minimizing snagging while maintaining a confident presence. The warm glow of 14K yellow gold complements the marquise’s sharp geometry, polished to a smooth finish that feels balanced and comfortable for daily wear.

Each lab-grown diamond reflects a commitment to ethical clarity and sustainability, grown with care to mirror the brilliance of mined stones without the environmental cost.

Designed for those who appreciate refined understatement, this solitaire mounting suits slender to medium finger sizes, its streamlined form ideal for stacking or wearing solo. The semi-set style invites personal choice, allowing you to select a marquise diamond that resonates with your vision.
