Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic shadow that dances along the finger. This three-stone semi-set engagement ring in 14K yellow gold frames a 10 x 5 mm marquise center stone, ready to be paired with your chosen lab-grown diamond.

Handcrafted in our Williamsburg studio, the band’s smooth, polished surface curves gently for a comfort fit that wears effortlessly every day. The three-stone setting balances presence with subtlety, allowing light to flood the marquise’s signature tapered shape, which visually elongates the hand with a refined, architectural grace.

Each piece is meticulously finished and inspected to ensure the prongs hold securely while maintaining a low profile that slips easily beneath gloves or alongside stackable bands. The warm glow of 14K yellow gold complements the diamond’s fire without overwhelming its delicate silhouette.

Our commitment to ethical jewelry is reflected in the lab-grown diamond option, offering clarity and brilliance with a smaller environmental footprint.

This ring suits those who appreciate a blend of classic drama and modern craftsmanship, especially for hands that favor slender, elegant shapes. Resizing is available to ensure a perfect fit, crafted with care in our Brooklyn workshop.
