Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, its tapered points drawing the eye along a graceful arc. This three-stone semi-set ring invites your choice of an 8 x 4 mm lab-grown marquise, poised between two delicate side stones that echo its refined geometry.

Crafted from warm 18K rose gold, the mounting features a low-profile setting that nestles close to the finger, finished with a smooth comfort fit for everyday wear. Each prong is meticulously hand-forged in our Williamsburg studio, ensuring secure hold without sacrificing elegance.

Our diamonds are sustainably grown, offering clarity and brilliance with a lighter environmental footprint. This ring’s slender band and balanced proportions suit slender to medium fingers, while its understated height allows for easy stacking or pairing with a wedding band.

Should you wish to adjust sizing, we accommodate custom fits with care to preserve the ring’s structural integrity. Lead times vary slightly depending on stone selection, but we keep you informed throughout the process.
