Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your hand as an 8 x 4 mm marquise diamond begins its halo embrace—an interplay of light and shadow that draws the eye without overwhelming. This semi-set engagement ring foundation features a 10K yellow gold band, crafted with a low-profile halo setting designed for everyday grace and resilience.

The band’s gentle curve and secure prong work ensure comfort fit and glove-friendly wear, while the halo’s delicate frame enhances the marquise’s tapered drama with a refined silhouette. Each piece is meticulously finished in our Williamsburg studio, where precision meets quiet strength in every contour and polish.

Our commitment to ethical jewelry is reflected in the lab-grown diamond clarity, offering a sustainable choice without compromise on brilliance or character.

Ideal for those seeking a ring that balances architectural elegance with practical wearability, this mounting suits slender to medium finger shapes and pairs effortlessly with stackable bands or wedding rings.
