Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your hand as a 12 x 6 mm marquise diamond catches the light with its tapered brilliance. This semi-set engagement ring in 14K white gold offers a refined foundation, designed to showcase your chosen center stone with delicate accent details that enhance without overwhelming.

Crafted in Williamsburg, the band features a low-profile setting that sits close to the finger, ensuring comfort for everyday wear and ease under gloves. The smooth finish and precise prong work reflect meticulous studio inspection, balancing security with elegance.

Each diamond is lab-grown, embodying a commitment to ethical sourcing and environmental mindfulness without compromising on clarity or sparkle.

Its slender silhouette suits hands seeking a graceful yet modern statement, pairing effortlessly with stackable bands or worn solo for understated sophistication.

Should you need resizing, our Brooklyn studio offers expert adjustments to maintain the ring’s integrity and fit.
