Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it draws the eye along a graceful arc—an elegant statement of refined confidence. This semi-set engagement ring foundation in 14K white gold offers a sleek, modern-minimal frame designed to showcase a 12 x 6 mm marquise center stone, accented subtly to enhance its architectural clarity.

Crafted with precision in Williamsburg, Brooklyn, the band’s clean lines and low-profile setting ensure comfortable daily wear without sacrificing presence. The polished finish reflects light softly, while the secure prong arrangement balances protection with visibility, inviting the diamond’s facets to sparkle freely.

Each piece features a lab-grown diamond foundation, embodying a commitment to ethical sourcing and environmental mindfulness without compromise on brilliance or durability.

Ideal for those who appreciate structured elegance and a confident silhouette, this mounting suits hands that favor elongated shapes and pairs well with stackable bands or a simple wedding band. Its streamlined design slips easily under gloves or sleeves, making it a versatile choice for everyday life.
