So many shades of sapphires are found in Celyon/Sri Lanka - including the beautiful purple/violet ones, so there is no reason why a sapphire in the blue/green or green/blue range would not be found there also.
It seems that just about any colour is possible with sapphires. I believe that in Africa vibrant orange ones can be found! Here in Australia black ones are also common and are now very popular in high quality jewels.
