Lab-Grown Diamond Engagement Ring

Light catches the elongated points of the marquise diamond, casting a slender, luminous silhouette across the hand. This three-stone engagement ring, set in polished platinum, balances architectural elegance with everyday resilience.

The center marquise measures a striking 12 by 6 millimeters, its tapered shape framed by two smaller stones that enhance brilliance without bulk. Crafted with a low-profile setting, the ring sits close to the finger, ensuring comfort beneath gloves or during daily tasks. Each platinum prong is hand-finished for secure hold and subtle shine, while the band’s smooth interior offers a comfort fit designed for continuous wear.

Our lab-grown diamonds provide a clear, sustainable alternative, reflecting a commitment to ethical jewelry without compromising on sparkle or clarity.

Ideal for those who appreciate refined geometry and a ring that moves seamlessly from studio to street, this design complements slender to medium finger shapes and layers effortlessly with stacking bands.

Should you need a size adjustment, our in-house artisans accommodate precise resizing to maintain the ring’s integrity and balance.
