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 ring invites you to choose a center stone measuring 10 by 5 millimeters—an ideal size that balances presence with everyday grace.

Crafted in warm 18K yellow gold, the slender band is designed for comfort and subtlety, its smooth finish reflecting a soft glow that complements the diamond’s sharp geometry. The low-profile setting keeps the stone close to the hand, making it glove-friendly and perfect for layering with other bands.

Each ring is shaped by expert hands in Williamsburg, where sustainable practices guide the creation of lab-grown diamonds—offering clarity and brilliance without compromise. This ethical choice aligns with a modern commitment to responsible luxury.

Its refined silhouette suits those who appreciate romantic understatement and architectural form, especially flattering on slender fingers or as a striking solitaire statement. The semi-set design allows you to select a marquise diamond that resonates personally, ensuring a truly bespoke experience.
