Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it carves a striking, confident line across the finger—an elegant gesture of modern minimalism. This semi-set engagement ring features a 9 x 4.5 mm marquise center, poised to showcase your chosen stone with clarity and architectural grace.

Crafted from warm 14K rose gold, the band is designed with subtle accent details that enhance the diamond’s brilliance without overwhelming its refined shape. The low-profile setting ensures everyday comfort and ease, while the smooth finish reflects the meticulous handwork of our Williamsburg studio artisans.

Each lab-grown diamond offers a sustainable alternative, embodying ethical clarity without compromise. This ring’s slender silhouette suits those who appreciate clean lines and a confident statement, especially flattering on slender fingers or when stacked with complementary bands.

Should you need resizing or prefer a custom accent arrangement, our Brooklyn studio welcomes your vision with a pressure-free design experience. Lead times are typically four to six weeks, allowing for careful craftsmanship and quality inspection.
