Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a poised brilliance that draws the eye along the finger’s natural line. This semi-set engagement ring foundation in 18K white gold offers a sleek, modern-minimal frame designed to highlight a 12 x 6 mm marquise center stone of your choosing.

Crafted with a low-profile setting, the band balances structural clarity with everyday comfort, finished to a smooth polish that feels as refined as it looks. The accent details are precise, enhancing the diamond’s architectural shape without distraction, while the secure prong setting ensures durability for daily wear.

Each ring begins with a responsibly sourced lab-grown diamond, reflecting a commitment to ethical jewelry that reduces environmental impact without compromising on clarity or fire.

Its slender silhouette suits hands that appreciate clean lines and confident geometry, ideal for stacking with complementary bands or worn solo for a statement of quiet sophistication. The low-profile design slips easily under gloves or sleeves, making it a practical choice for an active lifestyle.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure a perfect fit without altering the ring’s elegant proportions.
