Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your hand as a marquise diamond, measuring 9 by 4.5 millimeters, catches the light with its tapered points and brilliant facets. This semi-set platinum solitaire ring offers a refined foundation, ready to showcase a center stone that balances architectural drama with everyday grace.

Crafted in platinum for enduring strength and a cool, luminous finish, the mounting features a low-profile setting designed to sit close to the finger. Its streamlined silhouette ensures comfort during daily wear and pairs effortlessly with other bands or a wedding ring. Each piece is meticulously finished and inspected in our Williamsburg studio, where precision meets quiet durability.

Choosing a lab-grown diamond for this setting reflects a commitment to ethical jewelry—minimizing environmental impact without compromising on clarity or brilliance.

The slender marquise shape naturally elongates the finger, making this ring an excellent choice for those who appreciate a sleek, modern aesthetic with a touch of vintage-inspired elegance. Its comfort fit and low profile make it glove-friendly and ideal for active lifestyles.
