Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of an 8 x 4 mm marquise diamond, casting a slender, graceful shadow across the hand. This semi-set engagement ring offers a refined foundation to showcase your chosen center stone, framed by delicate accent diamonds that enhance its subtle sparkle.

Crafted in 18K yellow gold, the mounting balances durability with a low-profile design that rests comfortably against the finger, ideal for everyday wear. The setting’s precise prongs secure the marquise shape while maintaining a sleek profile that slips easily beneath gloves or alongside stackable bands.

Each piece reflects our commitment to ethical jewelry through the use of lab-grown diamonds, combining clarity and brilliance with a reduced environmental footprint. The warm tone of yellow gold complements the marquise’s tapered points, emphasizing its elegant elongation.

Designed for those who appreciate a blend of classic form and modern practicality, this ring suits slender to medium finger sizes and pairs effortlessly with other fine jewelry. Resizing is available to ensure a perfect fit without compromising the setting’s integrity.
