Lab-Grown Diamond Engagement Ring

Light catches the elongated marquise shape, casting a slender, graceful shadow that seems to dance with every movement. This semi-set three-stone engagement ring foundation in polished platinum awaits your choice of a 7 x 3.5 mm marquise center, designed to frame the stone with subtle elegance.

Crafted with a low-profile setting, the ring balances presence and wearability, its smooth platinum band shaped for comfort and daily grace. Each prong is meticulously finished to secure your stone while allowing maximum light to enhance its signature tapered drama.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, offering clarity and brilliance with a smaller environmental footprint.

The slender silhouette suits hands that appreciate refined geometry and works beautifully alongside stackable bands or as a standalone statement. Its modest height ensures glove-friendly wear and ease for everyday life.
