Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This solitaire semi-set ring offers a refined foundation for a 9 x 4.5 mm marquise stone, designed with a low-profile setting that sits close to the finger for everyday ease.

Crafted from 18K white gold, the mounting’s sleek band balances strength with subtle elegance, its smooth finish ensuring comfort throughout the day. The semi-set style invites your choice of center stone, allowing precise customization while maintaining a secure, expertly engineered fit.

Each lab-grown diamond option reflects a commitment to ethical sourcing and sustainability, embodying clarity and brilliance without compromise. The slender silhouette complements slender to medium finger shapes, and the low profile makes it glove-friendly and stackable with other bands.

Resizing is available to ensure a perfect fit, with careful attention to preserving the ring’s structural integrity. Typical lead times accommodate the custom selection process, allowing thoughtful collaboration in our Williamsburg studio or online.
