Lab-Grown Diamond Engagement Ring

Light catches the elongated curves of a marquise diamond, casting a slender, graceful shadow across the hand. This semi-set solitaire invites you to choose a center stone that echoes your unique story, its 9 by 4.5 mm proportions offering a striking balance of presence and elegance.

Crafted in warm 14K yellow gold, the mounting features a delicate yet secure prong setting designed to showcase the diamond’s tapered points while maintaining a low profile for everyday wear. The band’s smooth finish and subtle taper ensure comfort, making it an ideal choice for those who appreciate refined simplicity with a whisper of vintage charm.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that offer clarity and brilliance without compromise to the environment.

This solitaire suits hands that favor elongation and grace, pairing effortlessly with stackable bands or worn alone as a statement of quiet confidence. Its slender silhouette slips easily beneath gloves or sleeves, perfect for daily life in Williamsburg’s creative pulse.
