Lab-Grown Diamond Engagement Ring

Soft morning light catches the gentle curve of a 3.4 mm round diamond, poised to become the heart of your story. This semi-set solitaire ring invites you to select a center stone that will sparkle with classic brilliance, its facets echoing the quiet rhythm of a Brooklyn dawn.

Crafted in warm 14K rose gold, the band’s subtle blush complements the diamond’s fire, while the low-profile setting ensures a smooth silhouette against the skin. Finished by hand in Williamsburg, the ring balances delicate elegance with everyday comfort, its polished surface reflecting the care of expert artisans.

Each lab-grown diamond offers a conscious choice—ethical clarity born from innovation, reducing environmental impact without sacrificing radiance. The solitaire’s refined shape suits those who appreciate minimalist grace, ideal for stacking or wearing alone with ease.

Designed to fit comfortably beneath gloves or alongside wedding bands, this mounting adapts seamlessly to your lifestyle. Resizing is available to ensure a perfect embrace of your finger’s unique shape.
