A carat is a standard unit of weight used for diamonds and other gemstones. Depending on the cut of the diamond, it can seem smaller or larger than it actually is. Many times diamonds with same weight come with different diameters, so you can choose the best diamond for you and your engagement ring.
The diamond’s cut grade is also important in how big the diamond looks. When a diamond is cut ‘perfectly’, it can reflect a great amount of light and so it can look bigger and more brilliant.
Carat size is not the most important aspect of a diamond. Don’t forget about quality! Some larger diamonds have less light and sparkle, while some smaller ones are more fiery.
