Learn about diamonds
Cut can make a diamond look bigger. It means that you get a free boost in the other aspects of the 3Cs (color, carat and clarity) just by having a better cut.
The cut of a diamond refers not only to the shape of the diamond and number of facets, but also to the quality of the cut.
Colorless diamonds are generally more valuable and commonly used in jewelry as they have better reflective qualities.
For diamonds in the colorless range (D-F), they are priced at a higher premium. Personally, these are the gemstones I would love to get my hands on.
Carat is used to describe the weight of diamonds. Generally the larger the stone the greater value. Diamond carat weight is the measurement of how much a diamond weighs.
Each carat can be subdivided into 100 'points.' This allows very precise measurements to the hundredth decimal place.
Clarity measures the imperfections. The purest, the higher its value. GIA considers the number, size, color, reflectivity, and position of every flaw visible under 10x magnification.
In a certified diamond, the cracks are charted on the certificate and act as a fingerprint for identifying a particular stone.
