The term "carat" is specifically a measurement of a diamonds weight, and on it's own may not be able to accurately measure the size of a diamond. Diamond size is evaluated by viewing the diamond from the top as that is how diamonds us presented to us when it is set into a ring. Diamonds can actually look larger with a good cut.
Choosing the correct carat weight:
When it comes to diamonds biggest is not always best. Factors that may effect your decision are:
- Finger size
- Setting size
If you have a precise budget and you do not wish to compromise on the weight of the diamond, look at diamonds with a good cut, SI1-SI2 clarity, and a H or I colour grade.
The smaller the ring size the bigger the diamond will look.
Inspect diamonds that are sized at half-carat weights and also full-carat weight as the prices of them do jump high at these points. The carat weight is dispensed across the diamond.
