Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a 12mm round diamond waiting to be chosen, its facets ready to dance in a three-stone embrace. This semi-set engagement ring foundation is crafted from warm 18K rose gold, shaped by hand in our Williamsburg studio where each curve is refined for subtle elegance.

The three-stone setting balances presence with wearability, designed with low-profile prongs that cradle your center stone securely while allowing light to flood every angle. The band’s smooth finish and moderate width ensure comfort for daily wear, whether worn solo or stacked alongside meaningful bands.

Each piece reflects our commitment to ethical jewelry: the lab-grown diamond option offers clarity and brilliance without compromise to sustainability. This ring suits those who appreciate artisan craftsmanship and a design that feels both intimate and modern.

Should you wish to adjust the fit, resizing is available to ensure the ring sits perfectly. Lead times are tailored to your custom design journey, with attentive guidance at every step.
