Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of an oval diamond, its elongated silhouette casting a soft glow that seems to stretch across the skin. This semi-set solitaire ring invites you to select a 7 x 5 mm lab-grown oval diamond, known for its graceful elongation that subtly enhances the hand’s natural lines.

Crafted in warm 14K rose gold or cool 14K white gold, the mounting balances delicate elegance with everyday strength. The low-profile setting keeps the diamond close to the finger, offering a comfort fit that slips easily beneath gloves or alongside stackable bands. Each piece is meticulously finished by hand in our Williamsburg studio, ensuring smooth edges and a refined polish that catches light without catching on fabric.

Our diamonds are lab-grown with clarity and sustainability in mind, reflecting a commitment to ethical jewelry that honors both beauty and responsibility.

This ring suits those who appreciate subtle romance and modern craftsmanship—ideal for hands that favor a slender, elongated shape or for anyone seeking a solitaire that blends seamlessly with daily life.

Should you wish to adjust the fit, resizing is available to ensure your ring feels as natural as it looks.
