Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of an oval diamond, casting a gentle glow that seems to stretch across the hand. This semi-set platinum solitaire offers a refined stage for a 9 x 7 mm oval center, its modern-minimal silhouette defined by six slender prongs that hold the gem with architectural precision.

Crafted in platinum, the band is polished to a mirror finish, balancing durability with a lightweight feel that rests comfortably for daily wear. The six-prong setting elevates the diamond just enough to reveal its glassy depth without sacrificing a low-profile silhouette, making it glove-friendly and ideal for stacking with complementary bands.

Each piece is meticulously finished in our Williamsburg studio, where expert hands inspect every facet and setting to ensure seamless craftsmanship. The lab-grown diamond at the heart of this ring embodies clarity and brilliance, created with an ethical commitment to sustainability and responsible sourcing.

Designed for those who appreciate clean lines and confident structure, this solitaire suits a hand that values understated elegance and modern clarity. Its size and shape elongate the finger, offering a subtle yet striking presence.
