Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a slender beam that dances across the hand. This 8 x 4 mm marquise lab-grown diamond is set in a sleek 14K yellow gold band, its pointed ends framed by delicate accent stones that add subtle brilliance without distraction.

Crafted with a modern-minimalist approach, the low-profile setting ensures the ring sits comfortably for daily wear, while the polished yellow gold shank offers a warm contrast to the diamond’s icy clarity. Each piece is meticulously finished and inspected in our Williamsburg studio, where precision meets quiet confidence.

Our diamonds are sustainably created in controlled environments, offering the same optical performance as mined stones with a lighter environmental footprint.

The slim band and elongated marquise shape flatter slender fingers and work beautifully alongside wedding bands or stackable rings. Its refined structure makes it glove-friendly and ideal for those who prefer understated elegance with architectural clarity.

Should you need a custom fit, resizing is available to ensure the ring feels as natural as it looks.
