Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your finger as a marquise diamond begins to take shape, its tapered points drawing the eye with quiet drama. This semi-set engagement ring foundation in warm 14K yellow gold is crafted to hold a 6 x 3 mm marquise stone, offering a sleek, low-profile silhouette that sits close to the hand for everyday comfort.

The band’s smooth finish and secure prong setting ensure durability without bulk, making it an ideal choice for those who value a refined yet practical design. Each piece is meticulously inspected in our Williamsburg studio, where precision meets thoughtful engineering to balance wearability with elegance.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, minimizing environmental impact while delivering exceptional clarity and brilliance.

Designed for hands that appreciate subtle sophistication, this mounting complements slender fingers and pairs effortlessly with stackable bands or wedding rings. Its low profile also makes it glove-friendly, perfect for daily wear without catching or discomfort.

Should you need resizing, we handle adjustments with care to maintain the ring’s integrity and finish, ensuring it fits seamlessly into your life.
