Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous beam across the hand. This semi-set engagement ring in 14K yellow gold awaits your choice of a 10 x 5 mm marquise center, its pointed shape lending a graceful, tapered drama that visually elongates the finger.

Crafted with a low-profile setting designed for everyday wear, the band’s smooth finish and secure prongs ensure comfort and durability without excess height. The subtle accent stones frame the center elegantly, enhancing brilliance while maintaining a sleek, unobtrusive profile ideal for stacking or glove-friendly wear.

Each piece reflects our commitment to ethical jewelry through lab-grown diamonds, offering clarity and sparkle with a smaller environmental footprint. The warm glow of 14K yellow gold complements the marquise’s vintage-inspired shape, creating a harmonious balance between classic form and modern practicality.

Sized to fit comfortably, this mounting adapts well to various hand shapes and sizes, making it a versatile foundation for your custom design. Resizing is available to ensure a perfect fit, with careful finishing to preserve the band’s smooth contour.
