Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette across the hand. This three-stone engagement ring in polished platinum balances architectural grace with everyday resilience.

Each marquise center stone, measuring 9 by 4.5 millimeters, is securely nestled between two tapered side stones, creating a seamless flow along the finger. The low-profile setting minimizes snagging, while the comfort-fit band ensures a natural feel for daily wear. Expertly finished in our Williamsburg studio, the platinum surface is hand-polished to a subtle sheen that complements the diamond’s fiery brilliance.

Crafted exclusively with lab-grown diamonds, this ring reflects a commitment to ethical sourcing and environmental mindfulness without compromising on clarity or sparkle.

Its elongated shape visually lengthens the finger, ideal for those seeking a refined yet distinctive statement. The three-stone design offers versatility for stacking or pairing with a wedding band, while the secure setting supports active lifestyles.

Resizing is available to ensure a precise fit, with typical lead times tailored to your custom preferences.
