A diamond's clarity is determined by the degree to which it is free from naturally occurring inclusions, often called "nature's fingerprints". Diamonds that are absolutely clean are very much in demand and are therefore the most expensive. But most of the diamonds have inclusions and scratches, trace minerals or other tiny characteristics that can detract from the pure beauty of the diamond. The GIA report summarises the number, location, size, and type of inclusions present in a diamond.
