      Round Lab Diamond Engagement Rings

      The Round Lab-Grown Diamond Engagement Ring has been a classic for decades and the reason it’s stayed so popular is because it has the same brilliance, quality, and durability as natural diamonds. A round diamond is perfect because of its smooth, rounded edges, which means less chance of snagging on anything.

      Explore our luxury lab-grown round engagement rings at KARATERS to get a timeless look with a modern twist—classic style, ethical sourcing, and serious sparkle, all at an accessible price.
