How Are Diamond Sizes Measured?

Diamond sizes are measured in millimeters and refer to the diameter of a diamond. This is how large the diamond will appear when looked at from above. Diamond sizes are sometimes also referred to as its spread.

The Difference Between Diamond Sizes & Diamond Carats

Diamond sizes and diamond carats often go hand in hand but they are distinct traits. The diamond carat refers to the weight of the gemstone. The diamond size refers to its length and width. This means that two diamonds can be the same carat but be different sizes. Likewise, two diamonds may look the same size whilst being different carats.

The diamond shape is a key factor in determining the size and carat of the stone. For example, a 1 carat square diamond cut such as a princess or cushion is usually around 5.5mm in size. However, a 1 carat round cut diamond may be closer to 6.5mm in size. When you are choosing your perfect piece of jewelry, 1mm can make all the difference.
