Update on previous question: rinsed, more colorful rocks shown.

0 votes

I posted a question (http://answers.minerals.net/7747/could-someone-i-identify-any-all-of-these-rocks-in-this-bulk) yesterday asking for help identifying some rocks I ordered online in a bulk order. The pictures I posted had a dusty/chalky coating on all the rocks so it was difficult to identify them. After soaking them in water for a bit, they really showed their true colors and are much better to look at. Again, the list provided online said the order may include, but not limited to: Amethyst, Clear Quartz, Rose Quartz, Blue Quartz, Green Quartz, Sodalite, Orange Calcite, Fuchsite, Red Jasper, and Citrine. This order contains items from Brazil, if that helps identifying them. This is all for a little project I'm working on, would really like to know what their names are if possible.

I'm sure you can understand it is difficult to identify these rocks en masse. Please try to post one at a time so the posters here can open each one, no limit, and look at each one, to better offer their opinions. I would work on them singly, but so many at once is too much. That allows for our posters to view each rock in focus and enlarged. Thanks.

I will work on doing that. One separate question if I may ask: I'm trying to clean these rocks because when they arrived they all had a dusty/chalky coating on them which made the colors look so much more faded. I rinsed them and their colors popped out and looked a lot better. But as they air dried, they got dull again and looked to have the dusty coating again. No matter how many times I rinse/soak them (or for how long I've soaked them), they still return to that dull coating. I used an old toothbrush to scrape some of that dusty look off and that didn't help much. Do you have any suggestions that I could try? I want their colors to always be shown, not having to be rinsed so often. Thank you.
Unfortunately, every rock is different. Some are porous, meaning the water will penetrate the rock. So one type of treatment will work for one rock and not another.
Thanks, I'll wash them to get them wet and show off their better colors to take a picture. Then I'll post separate questions with these better images which can help identify them. Then maybe I can figure out how to clean them all properly.
