Can all specimens be verified from visuals

By far not. Some minerals are very distinctive and when they are in good condition, mineral experts can identify them easily, sometimes even their origin. So if you show me a mineral like fluorite, galena or tourmaline, I'm sure that I can identify them, maybe also where they came from. But this may only apply to a few hundreds among the many thousands of mineral species. Thus it is better to provide some information like hardness or streak and not only a visual impression when you want a mineral to be identified.

Hi, sorry it's not the mineral id that I meant, it's the locality id.
