Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic sparkle that draws the eye along the finger’s natural line. This semi-set solitaire ring invites you to select a center stone that measures 12 by 6 millimeters—its tapered points offering a refined balance of boldness and elegance.

Crafted in 14K yellow gold, the mounting is shaped with a delicate yet sturdy bezel that cradles the stone securely 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 artisan precision and a design that feels as natural as it looks.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that offer clarity and brilliance without compromise. This approach aligns with a sustainable ethos, quietly embedded in every facet and setting.

Designed for hands that favor statement simplicity, the marquise shape elongates the finger and pairs beautifully with stacking bands or a wedding band of your choice. Its slender form is glove-friendly and unobtrusive, perfect for daily life in Williamsburg’s creative pulse.
