[1.12.2]Getting name of an item from vanilla lang file?

[ErdbeerbaerLP]

Is it possible to load an item name of the current language from the vanilla lang file?
I want to make an troll diamond which should always called "Diamond" in any language selected. Because i only know german and english i cant add an lang file for ALL languages.

 

I already tried:
 

item.trolldiamond.name=item.diamond.name
------------------------------------------------------
item.trolldiamond.name=minecraft:item.diamond.name

Make your Item's unlocalized name the same as the diamond's unlocalized name.
