Lab-Grown Diamond Engagement Ring

The elongated silhouette of the marquise diamond, measuring 7 by 3.5 millimeters, captures light with a subtle, tapered brilliance that draws the eye along the finger’s natural line. This semi-set three-stone engagement ring foundation in 14K white gold offers a sleek, low-profile design crafted for everyday grace.

Each band is hand-finished in our Williamsburg studio, with smooth edges and a comfort fit that settles gently against the skin. The setting’s precise prongs are engineered to hold your chosen center stone securely while maintaining a streamlined profile that slips easily beneath gloves or sleeves.

Our commitment to ethical jewelry is reflected in the lab-grown diamond clarity and sustainability embedded in every piece, ensuring beauty with conscience.

Ideal for those who appreciate architectural elegance paired with practicality, this mounting complements slender to medium finger shapes and pairs well with stackable bands or wedding rings of varied widths.

Should you need resizing or prefer a custom consultation, our Brooklyn studio welcomes you to explore options with no pressure and full transparency on timelines.
