Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, graceful shadow that hints at quiet promises. This five-stone semi-set engagement ring in 14K white gold frames a 6 x 3 mm marquise center with delicate side stones, each facet reflecting light with a subtle, poetic shimmer.

Crafted in Williamsburg, the band’s smooth, low-profile design ensures a comfortable fit for daily wear, while the prong setting secures the stones with precision and elegance. The cool sheen of white gold complements the diamond’s crisp clarity, finished with meticulous hand polishing and thorough inspection to meet exacting standards.

Each diamond is lab-grown, offering a transparent origin and a smaller environmental footprint without compromising brilliance or character.

Its slender shape and refined setting suit hands that appreciate understated sophistication, pairing effortlessly with stacking bands or worn solo for a statement that is both modern and intimate. The low profile makes it glove-friendly and ideal for those seeking a ring that moves seamlessly through everyday moments.

Should you wish to adjust the fit, resizing is available to ensure the ring feels as natural as the commitment it represents.
