Pink diamond is an exceptionally rare and expensive diamond in the world. 
 

In 2022, pink diamond was auctioned for a staggering Rs 413 crore, setting a new record. 
 

Pink diamonds are mostly found in Argyle mine situated in the northwest region of Australia. Reportedly, 90 percent of the world’s pink diamonds are obtained from this mine. 
 

Shaping and cutting pink diamonds is a challenging process, which often takes 4 to 5 months. 
 

According to the scientists, the colour in diamonds is created by intense heat and pressure.
