Lab-Grown Diamond Engagement Ring
Morning light catches the subtle sparkle of a 5.2 mm round diamond, poised to become the centerpiece of a finely crafted engagement ring. This semi-set platinum mounting offers a low-profile silhouette, designed to sit comfortably beneath a glove or alongside a stack of bands without catching.
Each ring is meticulously forged in our Williamsburg studio, where the platinum is hand-polished to a soft sheen and the setting’s precision ensures the diamond will be secure yet showcased with maximum brilliance. The accent details add a refined texture, enhancing the center stone’s classic round cut—known for its lively fire and balanced symmetry.
Choosing a lab-grown diamond means embracing clarity and sustainability, with a gem that carries the same optical properties as mined stones but with a lighter environmental footprint.
This design suits those who value everyday elegance and practicality, with a comfort fit band that molds gently to the finger and a setting profile that minimizes snagging. The semi-set option invites you to select a center stone that reflects your personal story.
Resizing is straightforward, handled expertly in-studio to maintain the integrity of the platinum and setting.
