Sri Lankan sapphires have a significant influence on the global gem market. Because friends who have studied gems a little bit will know that Sri Lankan sapphires have the most valuable color in the world - cornflower blue, second only to Kashmir sapphires in quality. However, Kashmir sapphires only occupy a short period of time in the entire history of human gems. It took only five years from discovery to extinction, but these five years can be said to have raised the color cognition of sapphires for more than a thousand years to an unimaginable level - cornflower blue.
