Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends tracing a quiet elegance that seems to stretch beyond the hand. This semi-set solitaire invites you to choose a center stone that reflects your unique story, framed by a delicate 14K white gold band with a subtle warmth from rose gold accents.

Crafted in Williamsburg, the band’s slender profile balances presence with everyday ease, its smooth finish designed for comfort and gentle wear. The setting’s low profile keeps the diamond close to the finger, ideal for stacking or pairing with a wedding band without interruption.

Each piece is thoughtfully made with lab-grown diamonds, offering clarity and brilliance while honoring a commitment to sustainability and ethical sourcing. The marquise shape’s distinctive geometry elongates the finger, lending a refined grace to those who appreciate a blend of classic form and modern sensibility.

Resizing is available to ensure a perfect fit, and the semi-set design allows for personalized selection of your ideal diamond size and quality. Whether you visit our Williamsburg studio or explore the process online, the experience is tailored to your pace and vision.
