Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a 6 x 3 mm marquise diamond, it reveals a subtle drama that gracefully extends the hand’s natural line. This semi-set engagement ring offers a refined foundation to showcase your chosen center stone, framed by delicate accent details that enhance brilliance without bulk.

Crafted in 18K white gold, the mounting balances a low-profile design with secure prongs, ensuring daily comfort and ease beneath gloves or rings stacked alongside. The smooth finish and precise setting reflect careful handwork in our Williamsburg studio, where each piece is inspected for flawless wearability.

Our commitment to lab-grown diamonds means your ring carries a clarity and sparkle born from sustainable practices, reducing environmental impact without compromise.

Ideal for those seeking a sleek, modern silhouette that complements slender fingers or layered looks, this setting adapts effortlessly to a variety of personal styles and lifestyles.
