Barbra, I thought the green looked a little better.
Nikolaus, your answer for number six fits all the clues so far. So close! Annabergite at 2 would be the softest, is found at Laurium and is biaxial. I will have to nudge you a bit more to say that no. 6 is at least one full number higher on the Moh's scale than Annabergite and is orthorhombic.
Smithsonite for no. 1 is also getting close but incorrect. You have taken the building block clue to its natural conclusion but I find this blue-green to be fairly typical for Smithsonite, not unusual as the clue states. Sphalerite is not one of the 6.

Alright, no attempts for awhile now, so the answers are as follows:
Stone 1: Willemite, from Tsumeb, Namibia. The clue referenced the Franklin, New Jersey deposit which has produced gems as well as the Zinc in Willemite's struture
Stone 2: Blue Opal from Peru.
Stone 3: Smithsonite, also found in light pink.
Stone 4: Kornerupine
Stone 5: Chrysoprase from Australia. The "five cent's" reference was to Nickel as the coloring agent.
Stone 6: Adamite from Laurion, Greece. This is another of the Zinc minerals.
