Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a slender, dramatic sparkle that dances with every movement. This semi-set solitaire invites you to select a center stone that embodies your story, framed by a delicate 14K rose gold band that warms the hand with subtle blush tones.

Crafted in our Williamsburg studio, the band’s smooth, low-profile design ensures comfort for daily wear, while the artisan finish reveals fine hand polishing and precise prong settings ready to cradle your chosen gem securely. The rose gold’s gentle glow contrasts softly with the diamond’s sharp, tapered points, emphasizing the marquise’s signature elegance.

Each lab-grown diamond offers a sustainable alternative, grown with care to reduce environmental impact without sacrificing brilliance or clarity.

Ideal for those who appreciate refined geometry and a ring that layers effortlessly with wedding bands or stackable styles. The slender shank and modest height make it glove-friendly and unobtrusive for everyday life.

Should you need resizing, our in-house jewelers provide expert adjustments to ensure a perfect fit without compromising the ring’s integrity.
