Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of a 6x4 mm oval diamond, its soft brilliance framed by a delicate halo that seems to float above the finger. This engagement ring, set in cool 14K white gold, balances artisan precision with everyday grace.

Each piece is meticulously crafted in our Williamsburg studio, where the low-profile halo setting is hand-finished to ensure a smooth silhouette that rests comfortably against the skin. The band’s subtle taper enhances the diamond’s natural elongation, while the secure prong setting allows light to dance freely through the stone’s facets.

Our commitment to sustainability is reflected in the lab-grown diamond’s clarity and ethical origin, offering a conscious choice without compromise on sparkle or character.

Designed for those who appreciate refined craftsmanship and understated elegance, this ring suits slender to medium finger shapes and pairs effortlessly with stacking bands or a wedding band. Its comfort fit and modest height make it glove-friendly and ideal for daily wear.

Should you need a custom size, resizing is available with care to preserve the ring’s delicate proportions.
