Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This semi-set engagement ring foundation in 10K yellow gold offers a low-profile setting designed for everyday grace and resilience.

Crafted with precision in Williamsburg, the band’s smooth finish and secure prong arrangement ensure the 5 x 3 mm marquise center stone will sit close to the finger, minimizing snagging while maximizing comfort. The delicate accents frame the center with refined sparkle, enhancing the diamond’s signature brilliance without overwhelming its architectural shape.

Each piece features a lab-grown diamond option, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising clarity or fire. The warm yellow gold complements a variety of skin tones and suits those who appreciate a classic yet distinctive silhouette.

Ideal for hands that favor slender, elongated shapes, this mounting balances visual impact with practical wearability—stackable with other bands or worn solo for a statement of quiet confidence. Its modest profile fits comfortably under gloves and daily activities alike.

Resizing is available to ensure a precise fit, and the semi-set design invites you to select a marquise diamond that matches your personal vision. Typical lead times reflect careful hand-finishing and quality inspection in our Brooklyn studio.
