Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise diamond, its tapered points casting delicate shadows that dance across the hand. This three-stone engagement ring, set in cool platinum, balances bold geometry with refined craftsmanship.

Each stone is securely nestled in a low-profile setting, polished to a satin finish that softens the metal’s gleam while ensuring everyday comfort. The band’s subtle weight and smooth interior curve offer a gentle fit, designed for daily wear without compromise.

Crafted in our Williamsburg studio, the centerpiece is a 12 by 6 mm lab-grown marquise diamond, chosen for its dramatic silhouette and lively sparkle. The side stones echo the center’s shape, creating a harmonious trio that frames the finger with architectural grace.

Lab-grown diamonds provide a clear ethical advantage, reducing environmental impact while maintaining the brilliance and clarity expected from fine jewelry.

This ring suits those who appreciate sculptural elegance and a statement piece that remains practical—its low profile slips easily under gloves and stacks well with other bands.

Resizing is available to ensure a perfect fit, with careful hand finishing to preserve the ring’s seamless lines.
