Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it creates a striking interplay of brilliance and shadow that draws the eye along the finger’s natural line. This semi-set engagement ring foundation in 14K white gold is crafted to showcase a 10 x 5 mm marquise center stone, framed by delicate accent settings that enhance its sculptural elegance without overwhelming.

The band is designed with a low-profile setting to sit comfortably beneath gloves or daily wear, while the smooth finish and precise prong work ensure durability and ease of maintenance. Each piece undergoes meticulous hand inspection in our Williamsburg studio, where the focus is on refined craftsmanship and lasting wearability.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, offering clarity and sparkle with a smaller environmental footprint.

This ring base suits those who appreciate architectural form and subtle sophistication, ideal for stacking or wearing solo with a comfort-fit band that balances presence and practicality.
