The costliest diamonds are gem-quality stones rated with perfect colour -- for their colour category, flawless in clarity, excellence of cut and with a heavy carat weight.
Since the Koh-i-Noor is not for sale, it cannot be called the most costly diamond.
There are several reasons why a natural, gem-quality diamond is costly, the foremost being it's rarity. Only about 20% of all diamonds mined are gem-quality. Also, lab-created diamonds are less costly that natural diamonds. Industrial quality diamonds are not costly.
