Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of an 8 x 4 mm marquise diamond, casting a slender, luminous silhouette that gently elongates the finger. This semi-set halo ring in 18K yellow gold frames the center stone with a delicate circle of pavé, enhancing its tapered drama without adding bulk.

Crafted in Williamsburg, the band is polished to a smooth comfort fit, designed for daily wear with a low-profile setting that slips easily beneath gloves or sleeves. Each piece undergoes meticulous hand finishing and inspection to ensure the halo’s pavé stones sit securely and the gold’s warm tone remains radiant over time.

Choosing a lab-grown diamond means embracing clarity and brilliance with a lighter environmental footprint, reflecting a quiet commitment to ethical jewelry.

The marquise shape’s architectural elegance suits slender hands or those seeking a ring that visually lengthens the finger, while the halo setting adds subtle sparkle without overwhelming the design. Its semi-set nature invites you to select a center stone that resonates personally, making this ring a truly custom expression.

Resizing is straightforward, with the band’s solid gold construction allowing adjustments without compromising the setting’s integrity.
