What struck me about their publicity is that they do not know the locality for any of their specimens! Did they misplace the labels?

We could help them with some localities, I guess.

I have one - it is a volcanic bomb from a volcano in Fife, Scotland (Hill of Tarvit), so about 300 million years ago it must have shot out from the volcano

It might be easier for you to take the tray of minerals to a local mineral dealer or museum? They can then help you identify things. If that is not easy, keep doing tests and posting

If the second one in harder than quartz, then tourmaline is likely. For the first, which is less hard than quartz, it is unlikely.

Check their streaks as that may help a bit

Chalcedony is a form of microcrystalline quartz and this looks like quartz, so it might contain chalcedony. I have no idea where it is from as it could be from millions of different places

If you do a few tests we might be able to help - hardness should be the first test as that will help rule out the very hard minerals (I suspect it will rule out your guess).
