Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a delicate arc of light. This semi-set halo engagement ring foundation in 10K white gold offers a refined stage for a 6 x 3.5 mm marquise center stone, ready to be chosen and set with care.

Crafted in our Williamsburg studio, the band is hand-polished to a soft sheen, its low-profile setting designed for everyday grace and comfort. The halo setting, with its artisan precision, frames the marquise shape to amplify brilliance while maintaining a subtle presence on the finger.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that balance clarity with sustainability.

The slender band suits those who favor a refined silhouette, offering a comfortable fit that pairs beautifully with stacking rings or a wedding band. Its modest height ensures glove-friendly wear and ease in daily life.

Should you need resizing, our in-studio experts handle adjustments with care to preserve the ring’s delicate proportions.
