Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of three round diamonds poised to sparkle in unison, each stone ready to tell a story of shared moments. This semi-set engagement ring foundation in warm 18K yellow gold invites your choice of a 5.5 mm center diamond, framed by two smaller companions that balance brilliance with quiet elegance.

Handcrafted in our Williamsburg studio, the band’s smooth finish and subtle taper cradle the stones in a low-profile setting designed for everyday grace. The artisan’s touch is evident in the precise prong work, ensuring durability without sacrificing light’s dance across each facet.

Each diamond is lab-grown, offering clarity and fire with a mindful footprint that honors both beauty and sustainability. The three-stone design suits those who appreciate symbolism and balance, while the comfort fit band feels natural whether worn solo or stacked alongside other rings.

Should you need resizing, our in-studio experts handle adjustments with care to maintain the ring’s integrity. Lead times vary slightly depending on diamond selection, but we guide you through every step with transparency.
