Lab-Grown Diamond Engagement Ring

The elongated marquise shape, measuring 7 by 3.5 millimeters, draws the eye with its tapered points and elegant silhouette, lending a subtle drama to the hand. This semi-set solitaire ring features a 14K white gold band crafted for a low-profile fit, designed to sit close to the finger for everyday comfort without sacrificing presence.

Each band is meticulously formed and hand-finished in our Williamsburg studio, ensuring smooth edges and a balanced weight that feels natural from morning coffee to evening plans. The mounting’s secure prongs are engineered to cradle your chosen marquise diamond firmly while allowing maximum light to enhance its brilliance.

Our commitment to lab-grown diamonds means your center stone will offer exceptional clarity and sparkle with a significantly reduced environmental footprint. This ethical choice aligns with a modern approach to fine jewelry, marrying beauty with responsibility.

The slender band suits a variety of hand shapes and sizes, especially flattering elongated fingers, and its streamlined profile makes it ideal for stacking or pairing with a wedding band. Its subtle height also ensures glove-friendly wear and ease of daily movement.

Should you need resizing, our in-house artisans provide precise adjustments to maintain the ring’s integrity and comfort. Typical lead times reflect the care taken in crafting each piece to your specifications.
