The only blue ice that I know of is glacial ice - unless you are making ice cubes with food coloring.
Glaciers are formed from compaction of snow through intermediate stages of firn and neve under great pressure, rather than by freezing water into ice as you would find in your ice cube tray or on a frozen lake. The ice forms crystals and the crystals act as prisms, refracting the blue spectrum of normal white daylight.
Hope that helps!

It is not always blue! Ice is the color of the light it refracts (reflects) from the particles suspended in it. it's like if you put something like a blue crystal in water, light will often make the water look blue too.

I've never seen blue ice but if there is some, I'm sure it has to do with that particular piece acting as a prism.

Well, I just went into my freezer and pulled out an ice cube. My ice cubes aren't blue, they're clear. Hmmm....what kind of ice cubes do you have? I have never seen a blue ice cube.

The molecules in the ice are absorbing all colors except blue; the blue is being reflected. That is how anything shows color.
