Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set halo engagement ring foundation in platinum offers a refined stage for a 6 x 3 mm marquise center, designed to sit close to the finger with a low-profile setting that balances elegance and everyday comfort.

Crafted in platinum, the mounting features a secure halo frame that enhances the stone’s distinctive shape while maintaining a sleek, glove-friendly profile. The band’s smooth finish and subtle taper ensure it layers effortlessly with other rings or stands alone with quiet confidence. Each piece is meticulously inspected in our Williamsburg studio to meet exacting standards of fit and finish.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, combining clarity and sustainability without compromise.

Ideal for those who appreciate architectural lines and a modern silhouette, this halo mounting complements the marquise’s dramatic elongation, flattering slender fingers and offering versatile wearability for daily life.
