Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along a graceful arc. This semi-set halo engagement ring foundation in 10K white gold frames a 12 x 6 mm center stone with delicate pavé, designed to amplify the diamond’s fiery brilliance.

Handcrafted in our Williamsburg studio, the band’s smooth comfort fit and low-profile setting ensure daily wearability without catching. Each prong is meticulously finished to cradle the marquise securely while maintaining an airy, refined presence.

Our commitment to sustainability shines through the lab-grown diamond clarity, offering an ethical alternative with identical optical properties to mined stones.

The elongated marquise shape naturally elongates the finger, pairing beautifully with slender hands or stacked bands. Its halo setting adds dimension without overwhelming, making it a versatile choice for those who appreciate subtle drama.

Should you wish to customize the center stone or adjust sizing, we welcome consultations to tailor the ring precisely to your vision and fit.
