Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it reveals a quiet drama that stretches across the finger with refined elegance. This semi-set engagement ring features an 18K yellow gold band, chosen for its warm glow and enduring strength, designed to complement the 9 x 4.5 mm marquise center stone you select.

Crafted with a modern-minimal approach, the setting balances clarity and structure, allowing the diamond’s pointed ends to shine without distraction. The band’s smooth finish and subtle accents create a confident frame that feels comfortable for daily wear, while maintaining a low profile that slips easily beneath gloves or alongside stackable bands.

Each piece is carefully hand-finished in our Williamsburg studio, where precision meets thoughtful design. The semi-set style invites you to personalize your ring with a lab-grown diamond of your choice, ensuring ethical clarity and sustainability without compromise.

Ideal for those who appreciate architectural lines and a distinctive silhouette, this ring suits hands that welcome elongation and a touch of boldness. Resizing is available to ensure a perfect fit, crafted with care to maintain the integrity of the design.
