Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the hand’s natural lines. This semi-set platinum solitaire frame awaits your choice of a 12 x 6 mm center stone, crafted to cradle the gem securely while maintaining a sleek, low-profile presence.

Hand-forged in our Williamsburg studio, the platinum band is polished to a satiny finish, offering a subtle contrast to the diamond’s sharp geometry. The setting’s precision ensures comfort for daily wear, with a slender shank that balances strength and grace without excess bulk.

Each lab-grown diamond option embodies clarity and brilliance with a mindful footprint, reflecting our commitment to sustainable luxury. The marquise shape’s distinctive form elongates the finger, ideal for those who appreciate a bold yet refined statement.

Designed to pair effortlessly with stacking bands or worn solo, this mounting suits a wearer who values artisan craftsmanship and understated elegance. Resizing is available to ensure a perfect fit, tailored to your lifestyle.
