Hi Maria78 -
as dognose already stated - they are authentic!
If you see niello you have to check if it is "real" niello, (engraved pattern, filled with the niello paste) or only a chemical oxydized pattern - looking like niello. Often you can distinguish it by the blueish colour - real niello is black. Never buy niello online - you have to see it!
