Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a 12 x 6 mm marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This three-stone semi-set ring in warm 14K rose gold offers a refined balance between presence and practicality.

Crafted in Williamsburg, the band is shaped for comfort and low profile wear, ensuring it slips easily beneath gloves or daily tasks without catching. The setting’s precision allows the center stone to sit securely, flanked by two smaller diamonds that enhance its signature pointed elegance. Each piece is hand-finished and inspected for smooth edges and lasting durability.

Choosing a lab-grown diamond means embracing clarity and brilliance with a lighter environmental footprint, reflecting a modern approach to ethical jewelry.

Ideal for those who appreciate architectural form paired with everyday ease, this ring complements slender to medium finger shapes and layers seamlessly with stackable bands. Its low profile setting keeps it practical for active lifestyles.

Resizing is available to ensure a perfect fit, crafted with care in our Brooklyn studio.
