Lab-Grown Diamond Engagement Ring

Imagine the elongated silhouette of a marquise diamond catching the light as it gently curves along your finger, its tapered points lending a subtle drama to every gesture. This semi-set engagement ring features an 18K white gold band, meticulously hand-finished in our Williamsburg studio to a smooth, comfort fit that wears effortlessly day to night.

The setting is designed with delicate accent stones that frame the center diamond’s 12 x 6 mm span, enhancing its signature brilliance without overpowering its architectural elegance. The low-profile mounting keeps the ring close to the hand, making it ideal for stacking or wearing alongside a wedding band.

Crafted with lab-grown diamonds, this piece reflects a commitment to ethical jewelry—offering clarity and sparkle with a smaller environmental footprint. The cool sheen of white gold complements the marquise’s glassy facets, creating a refined balance between modern geometry and artisan detail.

Its slender band and secure prong setting suit a wearer who values both statement and subtlety, especially those with longer fingers or a preference for rings that glide comfortably under gloves. Resizing is available to ensure a precise fit, with careful attention to maintaining the ring’s structural integrity.
