Mithril is spelled M I T H R I L if you wont take my word for it read some of these books because reading is FUN.
The Hobbit by J.R.R Tolkien the creater.....of
along with the rest of the Lord of the Rings books.
The Shannara Series by Terry Brooks.
As well as in any AD&D texts,novels,by writers such as Margret Weis,Tracy Hickman,Gary Gygax,Ed Greenwood,R.A Salvatore to name a few.
In a Fantasy setting various things occur objects take on lives of their own.
Diamond could be worked into an Armor using enchantments...because enchantments are magic they could be used to alter the very substance of the diamond forming it to suit ones needs.
Using different forms of transmutation a type of magic,a skilled user could take any common stone and voila form it any way he or she chose to do so.
I believe you are thinking more in a real life situation true diamond armor would be nearly if not impossible and ilogical to make in our world using normal means.
But even using our methods you could make an diamond armor by simply setting the diamonds into various plates of armor already made.
You would create a diamond studded armor of whatever kind it was scale platemail and so on even without magic this could create problems for people.
In well light areas foes would be blinded even for a moment by the sparkling brightness.
Thank you for responding with what you thought was true .But in the future before you seek to instruct someone it might be wise if you collect your facts.
If you have any questions I am more than willing to answer them, if I cannot be of some help i\'ll point you where you need to go.

BTW : Transmutation is the art of transformation taking one substance and making it into another.Lead to gold and so on.It often uses alchemy,potions,brews,philosophers stone,
Using Transmutation or similer magic one takes,the material and melds it redristrubting the very matter making it take other forms.It is very closely linked with what we call science today.
In a magical world
Enchanter
Reaching into a small pewter bowl on his altar Farion the transmuter pinches some pink sand like substance between his fingers.Then reaching into a small brazier holding burning hot rock diamonds.Putting his hands together he wiggles his fingers.
While muttering a strange incatation \"0yril nemobdi kyu pilo\"
His hands begin to glow with a bright blue radiance that seeps into the diamonds.Concentrating he forms the image of the diamonds becoming a soft pliable gooey substance within the brazier.
