Carat Weight refers to size and weight. Larger diamonds are scarce, and therefore more valuable.
However, two diamonds with the same carat weight can vary greatly in value, depending on the color, clarity and most importantly, the cut.
A half-carat diamond with high color and clarity ratings may cost more than a three-quarter carat diamond with lower color and clarity ratings, but identical cut.
It’s simply a matter of deciding what matters most to you, size or quality, then finding the best combination of size, color and clarity to suit your budget.
