I just received my order on Amazon of an assorted bulk of 10-20 pieces of rough crystals from Brazil. On their description, it says the order may include Amethyst, Clear Quartz, Rose Quartz, Blue Quartz, Green Quartz, Sodalite, Orange Calcite, Fuchsite, Red Jasper, and Citrine. Some others not listed may also have been included which may not help with the guessing process. I'm certainly no expert and it is harder to tell with some of these because they are rough and chalky.
*Secondary question: How can I clean these to make them not as chalky and not ruin the crystals? In the description on Amazon it said the ones in the photo were soaked in water to show off their potential. Can I soak them all in a tub of water? For how long? Any pre/post treatment to help them?
If someone could help me identify these rocks I'd appreciate it! I bought this bulk as part of a project so what I received didn't matter to me exactly, but I would just like to know for the sake of knowing what they are. I appreciate any/all help.
UPDATE: I posted a new question with different photos, they've been washed and are more colorful now: http://answers.minerals.net/7749/update-previous-question-rinsed-more-colorful-rocks-shown
