Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise diamond, casting a slender beam that dances along the 14K yellow gold band. This engagement ring balances bold geometry with subtlety, its low-profile setting designed to sit comfortably beneath a sleeve or glove.

Crafted in Williamsburg, the ring features a 9 by 4.5 mm marquise lab-grown diamond, known for its tapered points and dramatic silhouette. The stone is securely nestled in a refined setting with delicate accent stones that enhance its length without adding bulk. The smooth band curves gently for a comfort fit, ideal for everyday wear.

Each piece is meticulously finished and inspected in-studio, ensuring the metal’s warm glow complements the diamond’s clarity and brilliance. The lab-grown origin reflects a commitment to ethical jewelry, reducing environmental impact without compromising on sparkle.

This ring suits those who appreciate architectural elegance paired with practical design—its slender profile and secure mounting make it a natural choice for active hands and stacking with other bands. The 14K yellow gold offers a classic warmth that pairs beautifully with a variety of skin tones.

Resizing is available to ensure a perfect fit, crafted with care in Brooklyn’s studio. Lead times vary slightly depending on customization but are communicated clearly throughout the process.
