Grading of a gem is done according to the intensity of its color. Sometimes, a gem is enhanced by putting pink color into it. This process is known as painting. Pink diamonds are mined in Argyle and therefore, whoever visits this place, definitely visits the mines. These exotic gems are also found in the mines of South Africa, Brazil, and Australia. As it an extremely rare diamond, it can cost around millions. A pink diamond is a symbol of love, delicateness, and grace. It is very popular with women worldwide. As it is not easily available, it is a very precious stone.

The blue diamond is also rare as the pink one. The element which makes them blue is boron. These diamonds are only found in Cullian mine near Pretoria.
