Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, confident sparkle that draws the eye along the finger’s natural line. This semi-set engagement ring offers a refined foundation, ready to showcase a 10 x 5 mm marquise stone with subtle accent details that enhance its architectural grace.

Crafted from 18K yellow gold, the band balances warmth with a modern-minimalist structure, its smooth finish and low-profile setting designed for everyday wear. The accents are carefully placed to complement the marquise’s tapered drama without overwhelming its clarity and shape, while the comfort fit ensures the ring settles gently against the skin.

Each piece is hand-finished in our Williamsburg studio, where precision meets quiet craftsmanship. The semi-set design invites you to select a lab-grown diamond of exceptional clarity and size, reflecting our commitment to ethical jewelry that respects both beauty and sustainability.

Ideal for those who appreciate clean lines and confident geometry, this ring suits slender to medium finger shapes and layers seamlessly with stackable bands or a wedding band. Its low profile also makes it glove-friendly and unobtrusive for daily life.

Should you need resizing or prefer a custom accent arrangement, our Brooklyn studio offers personalized consultations to ensure your ring fits perfectly and reflects your vision.
