Search for round lab diamonds

Both are real diamonds: the same carbon crystal, hardness and sparkle. A lab-grown diamond is grown above ground in weeks; a natural diamond formed underground over billions of years.

• Grading: both are graded for color, clarity, cut and carat by laboratories such as IGI and GIA.
• Price: lab-grown diamonds cost far less for the same size and grades.
