Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp edges of a 6 x 6 mm square diamond, its facets unfolding like a quiet promise. This five-stone semi-set ring in 18K rose gold offers a warm embrace, the soft blush of the metal cradling your choice of center stone with delicate precision.

Each band is hand-finished in our Williamsburg studio, polished to a satin sheen that balances subtle glow with everyday wearability. The low-profile setting ensures the ring sits comfortably beneath gloves or alongside stackable bands, designed for life’s intimate moments and daily rhythms.

Crafted with lab-grown diamonds, this piece reflects a commitment to clarity and sustainability, marrying ethical sourcing with Brooklyn’s artisanal spirit.

The square shape lends architectural grace, its clean lines framing the stone’s modern geometry while elongating the finger with quiet confidence. Ideal for those who appreciate refined structure without excess height.

Resizing is available to ensure a seamless fit, and our team is happy to guide you through the selection and setting process, whether in-studio or online.
