Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic sparkle that draws the eye along the finger’s natural line. This semi-set engagement ring in 18K white gold offers a refined stage for a 6 x 3.5 mm marquise center, its pointed ends balanced by delicate accent stones that enhance clarity without distraction.

Crafted with a low-profile setting, the band’s smooth finish and subtle taper ensure comfortable daily wear, while the secure prong arrangement protects the stone’s delicate tips. Each ring is meticulously polished and inspected in our Williamsburg studio, where precision meets quiet modernity.

Choosing a lab-grown diamond means embracing a cleaner origin with the same optical brilliance as mined stones, reflecting a commitment to ethical jewelry without compromise.

The slender shape and modest scale suit hands that appreciate architectural elegance and a ring that layers effortlessly with wedding bands or stackable pieces. Its comfort fit and low profile make it glove-friendly and unobtrusive for everyday life.

Should you wish to adjust the fit, resizing is available with care to maintain the band’s seamless silhouette.
