What makes sapphire pools blue?  

Sapphire pools are blue due to minerals and other contents.

There are many factors that affect the color of water in sapphire pools, lakes, rivers, and more. Usually, lakes and oceans appear blue due to reflecting light from the sky above, but sometimes you’ll end up with literal blue water thanks to some natural conditions. Things like minerals, sediments, algae, bacterial blooms, and other factors all play a part; for example, in Yellowstone National Park, a lot of the sapphire pools look that way thanks to their mineral content. Calcium carbonate is typically the largest culprit. Another common cause of blue water is something a lot less pleasant, like blue-green algae, which is dangerous!
