“How tall is a 200 lb man?”

Since weight is not an accurate predictor of height, there are nearly as many answers to that question as there are 200lb men.

And that’s the same problem with trying to figure out “how big” a one-carat diamond is. “Carat” is a measure of weight, not dimension and not all one carat diamonds have the same dimensions.

However, all one carat diamonds of the same shape (such as “round brilliant” or “marquise”) are approximately the same size. While there’s still some room for variation (like people, a diamond can be “tall and thin” or “short and fat”), it is possible to give a reasonable estimate of the dimensions of a 1-carat round brilliant vs. a 3-carat round briliant.

Diamond Size ChartAnd that’s what this brochure provides — a glimpse at the average dimensions of round brilliant diamonds.
