Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow that feels both intimate and striking. This semi-set solitaire invites you to select a center stone that echoes your personal story, framed by a delicate 10K rose gold band that warms the skin with a subtle blush.

Crafted in Williamsburg, Brooklyn, the slender shank is polished to a soft sheen, designed for everyday grace without excess height. The low-profile setting ensures the ring sits comfortably beneath gloves or alongside other bands, making it a versatile companion for daily wear. The rose gold’s gentle warmth contrasts softly with the diamond’s sharp geometry, balancing romance with modern clarity.

Each lab-grown diamond offers a sustainable alternative, created with precision and care to meet exacting standards of brilliance and ethical responsibility. This ring’s semi-set form allows you to choose a marquise diamond that suits your vision, whether you prefer a delicate sparkle or a bold statement.

Ideal for those who appreciate a refined silhouette and a ring that feels as natural as it is elegant, this design complements slender fingers and lends an elongating effect to the hand. Its modest profile and comfort fit make it suitable for stacking or solo wear.
