Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of an oval diamond, casting a subtle glow that seems to stretch across the finger. This semi-set solitaire invites you to select a 7.5 by 5.5 mm center stone, its shape known for elongating the hand with elegant poise.

Crafted in a fixed two-tone combination of 18k yellow and 18k yellow and platinum and 18k yellow and platinum, the band balances warmth and coolness with a refined six-prong setting that secures the stone while maintaining a lightweight profile. The low-set mounting ensures comfort for daily wear, while the polished finish reflects the Brooklyn studio’s meticulous handwork.

Each lab-grown diamond option offers a clarity and brilliance that aligns with a commitment to sustainable, ethical jewelry practices—an understated choice for conscious couples.

Designed for those who appreciate modern minimalism, this ring’s slender band and streamlined silhouette make it ideal for stacking or wearing alone. Its low profile fits comfortably under gloves and daily activities without catching.

Should you wish to resize, our in-house artisans provide precise adjustments to ensure a perfect fit without compromising the ring’s integrity.
