Oldies but Goodies - Amazonite

After skipping last week due to technical problems we are back with some amazonite and more for this Jewelry Artisans Community Oldies but Goodies Challenge.
Since the rules are not too strict, not all of those stones are amazonite - all of them have the aqua blue color, though. Can you find out what is what? Not that it really matters, important is how soothing and lovely that aqua is to the eyes. What comes to your mind when you see today's entries?
