Diamond Facets

      The princess cut can have from 50 to 144 facets. As you know, the facets in different diamond shapes act like mirrors that enhance the reflection of light. The higher the number of facets, the more diamond shines and sparkles.

      The number of facets of a princess diamond depends on the usage of the diamond and the skill of the person who cut the diamond. Generally, diamonds with more facets are used as a central diamond in the princess cut engagement ring (for example, a diamond with 76 or more facets). But if a diamond is used as a side stone on the diamond ring's band, then you can choose diamonds with less luminosity and sparkle (for example, with 50 facets).

       Keep in mind that the only determinant of diamond sparkle is not the number of diamond facets. Other factors such as shape, heart and arrow pattern, cut, etc. are also effective in the diamond sparkle.

Sparkle

Size

     If you compare a princess and round diamond with the same carat weight, you’ll realize that the round diamond will have a slightly larger face-up surface area. However, princess cuts can seem to be larger, because they have large diagonal measurements.  Therefore, you will still be able to buy a larger princess cut than a round cut while staying in your engagement ring budget.

Durability

     Since princess-cut diamond have sharp corners, they’re likely to be damaged. The solution is that theor corners should always be protected with prongs in order to reduce the risk of damage to the stone. Round diamonds on the other hand do not have any weak point to cause damage to the stone.
