1.52 Carat Actual Size
An average round diamond with a 1.52 carat size has a diameter of 7.5 mm; bear in mind that this can change depending on the cut. The ring shown in the picture is a US size six, which is equivalent to an L 1/2 ring size in places such as Britain and Australia. Be careful of reading too much into just a picture - a picture alone won't be entirely representative of every finger and hand type - you are best advised to get a bit of an idea in store with an actual ring. Also take into account the length and breadth of your fingers.
