Lab-Grown Diamond Engagement Ring

Sunlight catches the gently curved edges of this five-stone platinum semi-set, casting a quiet glow that promises a lifetime of shared moments. The 5.2 mm round center stone—known for its balanced brilliance and classic sparkle—awaits your choice, framed by four smaller companions that enhance its presence without overwhelming.

Crafted in platinum, the mounting offers a sleek, low-profile silhouette that rests comfortably against the finger, designed for everyday wear with a subtle modern-minimalist edge. Each prong is meticulously finished in-studio, ensuring secure settings that highlight the clarity and structure of the stones once set.

Our commitment to ethical jewelry is reflected in the lab-grown diamond option, providing a sustainable alternative with the same optical performance as mined stones.

This ring suits those who appreciate clean lines and confident design, ideal for stacking or wearing solo with ease. Its low profile makes it glove-friendly and unobtrusive, perfect for hands that move through daily life with purpose.
