    History, Types, Cultural Significance Of 4 Ct Lab-Grown Diamond Engagement Ring

    A 4 ct diamond is nothing short of extraordinary. It’s bold, radiant, and unforgettable—perfect for those who want their engagement ring to reflect a powerful, once-in-a-lifetime kind of love. And with lab-grown diamonds, you get the size and sparkle of your dreams—without overpaying or compromising your values.

    At The Karat Store, our 4 carat engagement ring collection includes:

    • Solitaire rings in oval, round, cushion, emerald, and princess cuts

    • Halo and double-halo styles for maximum brilliance

    • Three-stone rings that add balance and symbolism

    • Split-shank, cathedral, and twisted bands for added detail

    • Fully customizable options for your unique love story

    US shoppers choose lab-grown for good reason: these diamonds are chemically and visually identical to mined diamonds, yet sustainably created and more affordable. You get the best of both worlds—impact, intention, and incredible beauty.
