Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your finger as an 8 x 4 mm marquise diamond catches the light with its tapered, elegant silhouette. This semi-set engagement ring offers a refined foundation, ready to showcase your chosen center stone with delicate accent details that enhance its shape without overwhelming.

Crafted in 14K white gold, the mounting balances durability with a low-profile design that sits comfortably for daily wear. The setting’s clean lines and secure prongs ensure your diamond remains the focus while allowing light to enter freely, maximizing brilliance. Finished by hand in our Williamsburg studio, each piece undergoes meticulous inspection to meet exacting standards.

Our commitment to lab-grown diamonds means your ring carries a clear ethical advantage, reducing environmental impact without sacrificing clarity or fire.

Designed for those who appreciate subtle sophistication, this mounting suits slender to medium finger sizes and pairs effortlessly with stackable bands or a wedding ring. Its low profile fits comfortably under gloves and daily activities, making it a practical choice for an active lifestyle.

Should you need resizing or prefer a custom accent arrangement, our Brooklyn studio offers personalized consultations to ensure a perfect fit and finish.
