Lab-Grown Diamond Engagement Ring

Light catches the elongated points of a marquise diamond, casting a subtle, tapered shimmer that draws the eye along the finger’s natural line. This semi-set platinum solitaire mounting awaits your choice of a 6 x 3.5 mm marquise center, designed with a low-profile bezel setting that keeps the silhouette sleek and secure.

Crafted in platinum for enduring strength and a cool, luminous finish, the band features a comfort fit that rests gently against the skin, ideal for daily wear without catching or discomfort. The setting’s precision engineering ensures the stone sits close to the hand, balancing elegance with practicality.

Each ring is handcrafted in our Williamsburg studio, where expert jewelers inspect every detail to meet exacting standards. The lab-grown diamond option offers a clear, sustainable brilliance, reflecting a commitment to ethical jewelry without compromise.

This solitaire mounting suits those who appreciate refined geometry and a streamlined profile, perfect for stacking with complementary bands or worn solo for understated impact. Its narrow width and low height make it glove-friendly and unobtrusive for active lifestyles.

Should you need resizing, our Brooklyn studio provides careful adjustments to maintain the ring’s integrity and comfort. Typical lead times accommodate custom stone selection and finishing.
