Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to stretch the fingers with quiet elegance. This semi-set solitaire invites you to choose a center stone that balances vintage allure with modern clarity.

Crafted in warm 14K yellow gold, the band’s smooth polish contrasts gently with the crisp white gold prongs designed to cradle the marquise securely while maximizing light reflection. The low-profile setting ensures comfort for daily wear, slipping easily beneath gloves or alongside stackable bands.

Each piece is thoughtfully finished in our Williamsburg studio, where expert hands inspect every curve and facet to meet exacting standards. The lab-grown diamond option offers a brilliant, sustainable choice—minimizing environmental impact without compromising on sparkle.

Ideal for those who appreciate a ring that feels as personal as it looks, this solitaire suits slender to medium finger shapes, its elongated form flattering a variety of hand sizes. The semi-set design allows you to select a diamond that resonates with your unique vision.

Resizing is available to ensure a perfect fit, and our team is happy to guide you through care and customization options.
