Why is Lithium Chloride in white crystal form?

I am doing a paper tomorrow on lithium extraction, and so need to know some more about Lithium chloride. I am getting very confused here :(
Help would be appreciated :)

Lithium Chloride is very like the Sodium Chloride (common salt) that you are familiar with.
Crystals are colourless but faces are reflective so when crystals are small they look white.
