Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a 5.5 mm round diamond, its facets whispering quiet brilliance across a warm 18K yellow gold band. This five-stone semi-set invites your choice of center diamond, framed by four smaller companions that enhance its structured elegance without overwhelming.

Crafted in Williamsburg, the band’s smooth finish and low-profile setting ensure a comfortable fit for daily wear, while the secure prong work balances modern minimalism with enduring strength. Each piece undergoes meticulous hand inspection to meet exacting standards of clarity and polish.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, offering a sustainable alternative with the same optical fire and precision as mined stones.

Designed for those who appreciate clarity and confident structure, this ring suits hands that favor clean lines and subtle sparkle. Its low profile and balanced weight make it ideal for stacking or wearing solo, blending seamlessly with a variety of styles.

Should you need resizing or prefer a custom center stone, our Brooklyn studio offers personalized consultations to ensure your ring fits perfectly and reflects your vision.
